-\f2op\fP
-Specifies the accumulation buffer operation.
-Symbolic constants
-\%\f3GL_ACCUM\fP,
-\%\f3GL_LOAD\fP,
-\%\f3GL_ADD\fP,
-\%\f3GL_MULT\fP,
-and
-\%\f3GL_RETURN\fP are accepted.
-.TP
-\f2value\fP
-Specifies a floating-point value used in the accumulation buffer operation.
-\f2op\fP determines how \f2value\fP is used.
-.SH DESCRIPTION
-The accumulation buffer is an extended-range color buffer.
-Images are not rendered into it.
-Rather,
-images rendered into one of the color buffers
-are added to the contents of the accumulation buffer after rendering.
-Effects such as antialiasing (of points, lines, and polygons),
-motion blur,
-and depth of field can be created
-by accumulating images generated with different transformation matrices.
-.P
-Each pixel in the accumulation buffer consists of
-red, green, blue, and alpha values.
-The number of bits per component in the accumulation buffer
-depends on the implementation. You can examine this number
-by calling \%\f3glGetIntegerv\fP four times,
-with arguments \%\f3GL_ACCUM_RED_BITS\fP,
-\%\f3GL_ACCUM_GREEN_BITS\fP,
-\%\f3GL_ACCUM_BLUE_BITS\fP,
-and \%\f3GL_ACCUM_ALPHA_BITS\fP.
-Regardless of the number of bits per component,
-the range of values stored by each component is [\-1,\ 1].
-The accumulation buffer pixels are mapped one-to-one with frame buffer pixels.
-.P
-\%\f3glAccum\fP operates on the accumulation buffer.
-The first argument, \f2op\fP,
-is a symbolic constant that selects an accumulation buffer operation.
-The second argument, \f2value\fP,
-is a floating-point value to be used in that operation.
-Five operations are specified:
-\%\f3GL_ACCUM\fP, \%\f3GL_LOAD\fP, \%\f3GL_ADD\fP,
-\%\f3GL_MULT\fP, and \%\f3GL_RETURN\fP.
-.P
-All accumulation buffer operations are limited
-to the area of the current scissor box and applied identically to
-the red, green, blue, and alpha components of each pixel.
-If a \%\f3glAccum\fP operation results in a value outside the range [\-1,\ 1], 
-the contents of an accumulation buffer pixel component are undefined.
-.P
-The operations are as follows:
-.TP 14
-\%\f3GL_ACCUM\fP
-Obtains R, G, B, and A values
-from the buffer currently selected for reading (see \%\f3glReadBuffer\fP).
-Each component value is divided by $2 sup n^-^1$,
-where $n$ is the number of bits allocated to each color component
-in the currently selected buffer.
-The result is a floating-point value in the range [0,\ 1],
-which is multiplied by \f2value\fP and added to the corresponding pixel component
-in the accumulation buffer,
-thereby updating the accumulation buffer.
-.TP
-\%\f3GL_LOAD\fP 
-Similar to \%\f3GL_ACCUM\fP,
-except that the current value in the accumulation buffer is not used
-in the calculation of the new value.
-That is, the R, G, B, and A values from the currently selected buffer
-are divided by $2 sup n^-^1$,
-multiplied by \f2value\fP,
-and then stored in the corresponding accumulation buffer cell,
-overwriting the current value.
-.TP
-\%\f3GL_ADD\fP 
-Adds \f2value\fP to each R, G, B, and A
-in the accumulation buffer. 
-.TP
-\%\f3GL_MULT\fP 
-Multiplies each R, G, B, and A
-in the accumulation buffer by \f2value\fP and returns the scaled component
-to its corresponding accumulation buffer location.
-.TP
-\%\f3GL_RETURN\fP 
-Transfers accumulation buffer values
-to the color buffer or buffers currently selected for writing.
-Each R, G, B, and A component is multiplied by \f2value\fP,
-then multiplied by $2 sup n^-^1$,
-clamped to the range [0,$~2 sup n^-^1 $], and stored
-in the corresponding display buffer cell.
-The only fragment operations that are applied to this transfer are
-pixel ownership,
-scissor,
-dithering,
-and color writemasks.
-.P
-To clear the accumulation buffer, call \%\f3glClearAccum\fP with R, G, B,
-and A values to set it to, then call \%\f3glClear\fP with the
-accumulation buffer enabled. 
-.SH NOTES
-Only pixels within the current scissor box are updated by a
-\%\f3glAccum\fP operation.
-.SH ERRORS
-\%\f3GL_INVALID_ENUM\fP is generated if \f2op\fP is not an accepted value.
-.P
-\%\f3GL_INVALID_OPERATION\fP is generated if there is no accumulation buffer.

-\%\f3glArrayElement\fP commands are used within \%\f3glBegin\fP/\%\f3glEnd\fP pairs to

-Use \%\f3glArrayElement\fP to construct primitives by indexing vertex data, rather than

-.SH DESCRIPTION
-\%\f3glBegin\fP and \%\f3glEnd\fP delimit the vertices that define a primitive or
-a group of like primitives.
-\%\f3glBegin\fP accepts a single argument that specifies in which of ten ways the
-vertices are interpreted.
-Taking $n$ as an integer count starting at one,
-and $N$ as the total number of vertices specified,
-the interpretations are as follows:
-.TP 23
-\%\f3GL_POINTS\fP
-Treats each vertex as a single point.
-Vertex $n$ defines point $n$.
-$N$ points are drawn.
-.TP
-\%\f3GL_LINES\fP
-Treats each pair of vertices as an independent line segment.
-Vertices $2n^-^1$ and $2n$ define line $n$.
-$N/2$ lines are drawn.
-.TP
-\%\f3GL_LINE_STRIP\fP
-Draws a connected group of line segments from the first vertex
-to the last.
-Vertices $n$ and $n~+~1$ define line $n$.
-$N^-^1$ lines are drawn.
-.TP
-\%\f3GL_LINE_LOOP\fP
-Draws a connected group of line segments from the first vertex
-to the last,
-then back to the first.
-Vertices $n$ and $n~+~1$ define line $n$.
-The last line, however, is defined by vertices $N$ and $1$.
-$N$ lines are drawn.
-.TP
-\%\f3GL_TRIANGLES\fP
-Treats each triplet of vertices as an independent triangle.
-Vertices $3n^-^2$, $3n^-^1$, and $3n$ define triangle $n$.
-$N/3$ triangles are drawn.
-.BP
-.TP
-\%\f3GL_TRIANGLE_STRIP\fP
-Draws a connected group of triangles.  One triangle is defined for each
-vertex presented after the first two vertices.  For odd $n$, vertices
-$n$, $n~+~1$, and $n~+~2$ define triangle $n$.  For even $n$, vertices
-$n~+~1$, $n$, and $n~+~2$ define triangle $n$.  $N^-^2$ triangles are
-drawn.
-.TP
-\%\f3GL_TRIANGLE_FAN\fP
-Draws a connected group of triangles.
-One triangle is defined for each vertex presented after the first two vertices.
-Vertices $1$,
-$n~+~1$,
-and $n~+~2$ define triangle $n$.
-$N^-^2$ triangles are drawn.
-.TP
-\%\f3GL_QUADS\fP
-Treats each group of four vertices as an independent quadrilateral.
-Vertices $4n^-^3$, $4n^-^2$, $4n^-^1$, and $4n$
-define quadrilateral $n$.
-$N/4$ quadrilaterals are drawn.
-.TP
-\%\f3GL_QUAD_STRIP\fP
-Draws a connected group of quadrilaterals.
-One quadrilateral is defined for each pair of vertices presented
-after the first pair.
-Vertices $2n^-^1$, $2n$, $2n~+~2$, and $2n~+~1$ define quadrilateral $n$.
-$N/2^-^1$ quadrilaterals are drawn.
-Note that the order in which vertices are used to construct a quadrilateral
-from strip data is different from that used with independent data.
-.TP
-\%\f3GL_POLYGON\fP
-Draws a single,
-convex polygon.
-Vertices $1$ through $N$ define this polygon.
-.P
-Only a subset of GL commands can be used between \%\f3glBegin\fP and \%\f3glEnd\fP.
-The commands are
-\%\f3glVertex\fP,
-\%\f3glColor\fP,
-\%\f3glIndex\fP,
-\%\f3glNormal\fP,
-\%\f3glTexCoord\fP,
-\%\f3glEvalCoord\fP,
-\%\f3glEvalPoint\fP,
-\%\f3glArrayElement\fP,
-\%\f3glMaterial\fP, and
-\%\f3glEdgeFlag\fP.
-Also,
-it is acceptable to use
-\%\f3glCallList\fP or
-\%\f3glCallLists\fP to execute
-display lists that include only the preceding commands.
-If any other GL command is executed between \%\f3glBegin\fP and \%\f3glEnd\fP,
-the error flag is set and the command is ignored.
-.P
-Regardless of the value chosen for \f2mode\fP,
-there is no limit to the number of vertices that can be defined
-between \%\f3glBegin\fP and \%\f3glEnd\fP.
-Lines,
-triangles,
-quadrilaterals,
-and polygons that are incompletely specified are not drawn.
-Incomplete specification results when either too few vertices are
-provided to specify even a single primitive or when an incorrect multiple 
-of vertices is specified. The incomplete primitive is ignored; the rest are drawn.
-.P
-The minimum specification of vertices
-for each primitive is as follows:
-1 for a point,
-2 for a line,
-3 for a triangle,
-4 for a quadrilateral,
-and 3 for a polygon.
-Modes that require a certain multiple of vertices are
-\%\f3GL_LINES\fP (2),
-\%\f3GL_TRIANGLES\fP (3),
-\%\f3GL_QUADS\fP (4),
-and \%\f3GL_QUAD_STRIP\fP (2).
-.SH ERRORS

-\f2target\fP
-Specifies the target to which the texture is bound.
-Must be either
-\%\f3GL_TEXTURE_1D\fP,
-\%\f3GL_TEXTURE_2D\fP, or
-\%\f3GL_TEXTURE_3D\fP.
-.TP
-\f2texture\fP
-Specifies the name of a texture. 
-.SH DESCRIPTION
-\%\f3glBindTexture\fP lets you create or use a named texture. Calling \%\f3glBindTexture\fP with 
-.br
-\f2target\fP set to
-\%\f3GL_TEXTURE_1D\fP, \%\f3GL_TEXTURE_2D\fP, \%\f3GL_TEXTURE_3D\fP and \f2texture\fP
-set to the name
-of the newtexture binds the texture name to the target.  
-When a texture is bound to a target, the previous binding for that
-target is automatically broken.
-.P
-Texture names are unsigned integers. The value zero is reserved to
-represent the default texture for each texture target.
-Texture names and the corresponding texture contents are local to
-the shared display-list space (see \%\f3glXCreateContext\fP) of the current
-GL rendering context;
-two rendering contexts share texture names only if they
-also share display lists.
-.P
-You may use \%\f3glGenTextures\fP to generate a set of new texture names.
-.P
-When a texture is first bound, it assumes the dimensionality of its
-target:  A texture first bound to \%\f3GL_TEXTURE_1D\fP becomes
-one-dimensional, and a texture first bound to \%\f3GL_TEXTURE_2D\fP becomes
-two-dimensional, and a texture first bound to \%\f3GL_TEXTURE_3D\fP becomes
-a three-dimensional texture. The state of a one-dimensional texture
-immediately after it is first bound is equivalent to the state of the
-default \%\f3GL_TEXTURE_1D\fP at GL initialization, and similarly for 
-two-, and three-dimensional textures.
-.P
-While a texture is bound, GL operations on the target to which it is
-bound affect the bound texture, and queries of the target to which it
-is bound return state from the bound texture. If texture mapping of
-the dimensionality of the target to which a texture is bound is
-active, the bound texture is used.
-In effect, the texture targets become aliases for the textures currently
-bound to them, and the texture name zero refers to the default textures
-that were bound to them at initialization.
-.P
-A texture binding created with \%\f3glBindTexture\fP remains active until a different
-texture is bound to the same target, or until the bound texture is
-deleted with \%\f3glDeleteTextures\fP.
-.P
-Once created, a named texture may be re-bound to the target of the
-matching dimensionality as often as needed.
-It is usually much faster to use \%\f3glBindTexture\fP to bind an existing named
-texture to one of the texture targets than it is to reload the texture image
-using \%\f3glTexImage1D\fP, \%\f3glTexImage2D\fP, or \%\f3glTexImage3D\fP.
-For additional control over performance, use
-\%\f3glPrioritizeTextures\fP.

-\%\f3glBindTexture\fP is included in display lists.

-\%\f3glBindTexture\fP is available only if the GL version is 1.1 or greater.

-.SH DESCRIPTION
-A bitmap is a binary image.
-When drawn,
-the bitmap is positioned relative to the current raster position,
-and frame buffer pixels corresponding to 1's in the bitmap are
-written using the current raster color or index.
-Frame buffer pixels corresponding to 0's in the bitmap are not modified.
-.P
-\%\f3glBitmap\fP takes seven arguments.
-The first pair specifies the width and height of the bitmap image.
-The second pair specifies the location of the bitmap origin relative
-to the lower left corner of the bitmap image.
-The third pair of arguments specifies \f2x\fP and \f2y\fP offsets to be added
-to the current raster position after the bitmap has been drawn.
-The final argument is a pointer to the bitmap image itself.
-.P
-The bitmap image is interpreted like image data for the \%\f3glDrawPixels\fP
-command,
-with \f2width\fP and \f2height\fP corresponding to the width and height arguments
-of that command,
-and with \f2type\fP set to \%\f3GL_BITMAP\fP
-and \f2format\fP set to \%\f3GL_COLOR_INDEX\fP.
-.BP
-Modes specified using \%\f3glPixelStore\fP affect the
-interpretation of bitmap image data;
-modes specified using \%\f3glPixelTransfer\fP do not.
-.P
-If the current raster position is invalid, \%\f3glBitmap\fP is ignored.
-Otherwise,
-the lower left corner of the bitmap image is positioned at the window coordinates
-.ce

-$ x sub w ~=~ \(lf ~ x sub r ~-~ x sub o ~ \(rf $
-.br
-.sp
-.ce
-$ y sub w ~=~ \(lf ~ y sub r ~-~ y sub o ~ \(rf $
-.sp
-where $ ( x sub r , y sub r ) $ is the raster position
-and $ ( x sub o , y sub o ) $ is the bitmap origin.
-Fragments are then generated for each pixel corresponding to a 1 (one)
-in the bitmap image.
-These fragments are generated using the current raster \f2z\fP coordinate,
-color or color index, and current raster texture coordinates.
-They are then treated just as if they had been generated
-by a point, line, or polygon,
-including texture mapping,
-.br
-fogging,
-and all per-fragment operations such as alpha and depth testing.
-.P
-After the bitmap has been drawn,
-the \f2x\fP and \f2y\fP coordinates of the current raster position are offset by
-\f2xmove\fP and \f2ymove\fP.
-No change is made to the \f2z\fP coordinate of the current raster position,
-or to the current raster color, texture coordinates, or index.
-.SH NOTES
-To set a valid raster position outside the viewport, first set a valid
-raster position inside the viewport, then call \%\f3glBitmap\fP with NULL

-.P
-Transparency is best implemented using blend function
-(\%\f3GL_SRC_ALPHA\fP, \%\f3GL_ONE_MINUS_SRC_ALPHA\fP)
-with primitives sorted from farthest to nearest.
-Note that this transparency calculation does not require
-the presence of alpha bitplanes in the frame buffer.
-.P
-Blend function
-(\%\f3GL_SRC_ALPHA\fP, \%\f3GL_ONE_MINUS_SRC_ALPHA\fP)
-is also useful for rendering antialiased points and lines
-in arbitrary order.
-.P
-Polygon antialiasing is optimized using blend function
-.br
-(\%\f3GL_SRC_ALPHA_SATURATE\fP, \%\f3GL_ONE\fP)
-with polygons sorted from nearest to farthest.
-(See the \%\f3glEnable\fP, \%\f3glDisable\fP reference page and the 
-\%\f3GL_POLYGON_SMOOTH\fP argument for information on polygon antialiasing.)
-Destination alpha bitplanes,
-which must be present for this blend function to operate correctly,
-store the accumulated coverage.
-.SH NOTES
-Incoming (source) alpha is correctly thought of as a material opacity,
-ranging from 1.0 ($K sub A$), representing complete opacity,
-to 0.0 (0), representing complete 
-transparency.
-.P
-When more than one color buffer is enabled for drawing,
-the GL performs blending separately for each enabled buffer,
-using the contents of that buffer for destination color.
-(See \%\f3glDrawBuffer\fP.)
-.P
-Blending affects only RGBA rendering.
-It is ignored by color index renderers.
-.P
-\%\f3GL_CONSTANT_COLOR\fP, \%\f3GL_ONE_MINUS_CONSTANT_COLOR\fP,
-\%\f3GL_CONSTANT_ALPHA\fP, \%\f3GL_ONE_MINUS_CONSTANT_ALPHA\fP are only

-\f2equation\fP
-Specifies the address of an array of four double-precision floating-point values.

-.SH DESCRIPTION
-Geometry is always clipped against the boundaries of a six-plane frustum
-in \f2x\fP, \f2y\fP, and \f2z\fP.  
-\%\f3glClipPlane\fP allows the specification of additional planes,
-not necessarily perpendicular to the \f2x\fP, \f2y\fP, or \f2z\fP axis,
-against which all geometry is clipped.
-To determine the maximum number of additional clipping planes, call
-\%\f3glGetIntegerv\fP with argument \%\f3GL_MAX_CLIP_PLANES\fP. All
-implementations support at least six such clipping planes. 
-Because the resulting clipping region is the intersection
-of the defined half-spaces,
-it is always convex.
-.P
-\%\f3glClipPlane\fP specifies a half-space using a four-component plane equation.
-When \%\f3glClipPlane\fP is called,
-\f2equation\fP is transformed by the inverse of the modelview matrix
-and stored in the resulting eye coordinates.
-Subsequent changes to the modelview matrix have no effect on the
-stored plane-equation components.
-If the dot product of the eye coordinates of a vertex with the
-stored plane equation components is positive or zero,
-the vertex is \f2in\f1 with respect to that clipping plane.
-Otherwise, it is \f2out\fP.
-.P 
-To enable and disable clipping planes, call
-\%\f3glEnable\fP and \%\f3glDisable\fP with the argument 
-\%\f3GL_CLIP_PLANE\fP\f2i\fP, 
-where \f2i\fP is the plane number.
-.P
-All clipping planes are initially defined as (0, 0, 0, 0) in eye coordinates
-and are disabled.

-\%\f3glColor\fP has two major variants:

-\f2table\fP
-Pointer to a one-dimensional array of pixel data that is processed to

-.SH DESCRIPTION
-\%\f3glColorTable\fP may be used in two ways: 
-to test the actual size and color resolution of a lookup table
-given a particular set of parameters,
-or to load the contents of a color lookup
-table.
-Use the targets \%\f3GL_PROXY_*\fP for the first case
-and the other targets for the second case. 
-.P
-If \f2target\fP is \%\f3GL_COLOR_TABLE\fP,
-\%\f3GL_POST_CONVOLUTION_COLOR_TABLE\fP,
-or
-\%\f3GL_POST_COLOR_MATRIX_COLOR_TABLE\fP,
-\%\f3glColorTable\fP builds a color lookup table from an array of pixels.
-The pixel array specified by \f2width\fP, \f2format\fP, \f2type\fP, and \f2table\fP
-is extracted from memory and
-processed just as if \%\f3glDrawPixels\fP were called, but processing
-stops after the final expansion to RGBA is completed.
-.P
-The four scale parameters and the four bias parameters that are defined
-for the table are then used to scale and bias the R, G, B, and A components 
-of each pixel.
-(Use \%\f3glColorTableParameter\fP to set these scale and bias
-parameters.)
-.P
-Next, the R, G, B, and A values are clamped to the range [0,\ 1].
-Each pixel is then converted to the internal  specified by
-\f2internalformat\fP.

-Pointer to a one-dimensional array of pixel data that is processed to

-.SH DESCRIPTION
-\%\f3glConvolutionFilter1D\fP builds a one-dimensional convolution filter kernel from an array of
-pixels.
-.sp
-The pixel array specified by \f2width\fP, \f2format\fP, \f2type\fP, and \f2image\fP
-is extracted from memory and
-processed just as if \%\f3glDrawPixels\fP were called, but processing
-stops after the final expansion to RGBA is completed.
-.sp
-The R, G, B, and A components of each pixel are next scaled by the four
-1D \%\f3GL_CONVOLUTION_FILTER_SCALE\fP parameters and biased by the
-four 1D \%\f3GL_CONVOLUTION_FILTER_BIAS\fP parameters.
-(The scale and bias parameters are set by \%\f3glConvolutionParameter\fP
-using the \%\f3GL_CONVOLUTION_1D\fP target and the names
-\%\f3GL_CONVOLUTION_FILTER_SCALE\fP and \%\f3GL_CONVOLUTION_FILTER_BIAS\fP.
-The parameters themselves are vectors of four values that are applied to red,
-green, blue, and alpha, in that order.)
-The R, G, B, and A values are not clamped to [0,1] at any time during this
-process.
-.sp
-Each pixel is then converted to the internal  specified by
-\f2internalformat\fP.
-This conversion simply maps the component values of the pixel (R, G, B,
-and A) to the values included in the internal  (red, green, blue,
-alpha, luminance, and intensity).  The mapping is as follows:
-.sp
-.TS
-center;
-lb cb cb cb cb cb cb

-Internal Format	Red	Green	Blue	Alpha	Luminance	Intensity

-\%\f3GL_INTENSITY\fP						R

-\%\f3GL_RGBA\fP	R	G	B	A

-.TE
-.sp
-The red, green, blue, alpha, luminance, and/or intensity components of
-the resulting pixels are stored in floating-point rather than integer
-.
-They form a one-dimensional filter kernel image indexed with coordinate
-\f2i\fP such that \f2i\fP starts at 0 and increases from left to right.
-Kernel location \f2i\fP is derived from the \f2i\fPth pixel, counting from 0.
-.PP
-Note that after a convolution is performed, the resulting color
-components are also scaled by their corresponding
-\%\f3GL_POST_CONVOLUTION_c_SCALE\fP parameters and biased by their
-corresponding \%\f3GL_POST_CONVOLUTION_c_BIAS\fP parameters (where
-\f2c\fP takes on the values \f3RED\fP, \f3GREEN\fP, \f3BLUE\fP, and
-\f3ALPHA\fP).
-These parameters are set by \%\f3glPixelTransfer\fP.

-\f2image\fP
-Pointer to a two-dimensional array of pixel data that is processed to
-build the convolution filter kernel.
-.SH DESCRIPTION
-\%\f3glConvolutionFilter2D\fP builds a two-dimensional convolution filter kernel from an array of
-pixels.
-.sp
-The pixel array specified by \f2width\fP, \f2height\fP, \f2format\fP, \f2type\fP, and
-\f2image\fP is extracted from memory and processed just as if
-\%\f3glDrawPixels\fP were called, but processing stops after the final
-expansion to RGBA is completed.
-.sp
-The R, G, B, and A components of each pixel are next scaled by the four
-2D \%\f3GL_CONVOLUTION_FILTER_SCALE\fP parameters and biased by the
-four 2D \%\f3GL_CONVOLUTION_FILTER_BIAS\fP parameters.
-(The scale and bias parameters are set by \%\f3glConvolutionParameter\fP
-using the \%\f3GL_CONVOLUTION_2D\fP target and the names
-\%\f3GL_CONVOLUTION_FILTER_SCALE\fP and \%\f3GL_CONVOLUTION_FILTER_BIAS\fP.
-The parameters themselves are vectors of four values that are applied to red,
-green, blue, and alpha, in that order.)
-The R, G, B, and A values are not clamped to [0,1] at any time during this
-process.
-.sp
-Each pixel is then converted to the internal  specified by
-\f2internalformat\fP.
-This conversion simply maps the component values of the pixel (R, G, B,
-and A) to the values included in the internal  (red, green, blue,
-alpha, luminance, and intensity).  The mapping is as follows:
-.sp
-.TS
-center;
-lb cb cb cb cb cb cb
-l c c c c c c.
-_
-Internal Format	Red	Green	Blue	Alpha	Luminance	Intensity
-_
-\%\f3GL_ALPHA\fP				A
-\%\f3GL_LUMINANCE\fP				R
-\%\f3GL_LUMINANCE_ALPHA\fP			A	R
-\%\f3GL_INTENSITY\fP						R
-\%\f3GL_RGB\fP	R	G	B
-\%\f3GL_RGBA\fP	R	G	B	A
-_
-.TE
-.sp
-The red, green, blue, alpha, luminance, and/or intensity components of
-the resulting pixels are stored in floating-point rather than integer
-.
-They form a two-dimensional filter kernel image indexed with coordinates
-\f2i\fP and \f2j\fP such that \f2i\fP starts at zero and increases from left
-to right, and \f2j\fP starts at zero and increases from bottom to top.
-Kernel location \f2i,j\fP is derived from the \f2N\fPth pixel,
-where \f2N\fP is \f2i\fP+\f2j\fP*\f2width\fP.
-.PP
-Note that after a convolution is performed, the resulting color
-components are also scaled by their corresponding
-\%\f3GL_POST_CONVOLUTION_c_SCALE\fP parameters and biased by their
-corresponding \%\f3GL_POST_CONVOLUTION_c_BIAS\fP parameters (where
-\f2c\fP takes on the values \f3RED\fP, \f3GREEN\fP, \f3BLUE\fP, and
-\f3ALPHA\fP).
-These parameters are set by \%\f3glPixelTransfer\fP.

-\%\f3glSeparableFilter2D\fP for details.
-In these cases, \f2params\fP is an array of four values to be applied to

-\%\f3GL_CONVOLUTION_FILTER_SCALE\fP is (1, 1, 1, 1), and the initial value
-for \%\f3GL_CONVOLUTION_FILTER_BIAS\fP is (0, 0, 0, 0). 
-.sp
-A \f2pname\fP value of \%\f3GL_CONVOLUTION_BORDER_MODE\fP controls the
-convolution border mode. The accepted modes are:
-.TP
-\%\f3GL_REDUCE\fP
-The image resulting from convolution is
-smaller than the source image.
-If the filter width is $Wf$ and height is $Hf$,
-and the source image width is $Ws$ and height is $Hs$,
-then the convolved image width will be $Ws ~-~ Wf ~+~ 1$ and height
-will be $Hs ~-~ Hf ~+~ 1$.
-(If this reduction would generate an image with zero or negative width
-and/or height, the output is simply null, with no error generated.)
-The coordinates of the image resulting from convolution are zero
-through $Ws ~-~ Wf$ in width and zero through $Hs ~-~ Hf$ in
-height.
-.TP
-\%\f3GL_CONSTANT_BORDER\fP
-The image resulting from convolution is the same size as the source image, and
-processed as if the source image were surrounded by pixels with their color
-specified by the \%\f3GL_CONVOLUTION_BORDER_COLOR\fP.
-.TP
-\%\f3GL_REPLICATE_BORDER\fP
-The image resulting from convolution is the same size as the source image, and
-processed as if the outermost pixel on the border of the source image were
-replicated.
-.SH NOTES
-\%\f3glConvolutionParameter\fP is present only if \%\f3GL_ARB_imaging\fP is returned when \%\f3glGetString\fP
-is called with an argument of \%\f3GL_EXTENSIONS\fP.
-.P
-In cases where errors can result from the specification of invalid
-image dimensions, it is the dimensions after convolution that are
-tested, not the dimensions of the source image.
-For example, \%\f3glTexImage1D\fP requires power-of-two image size.
-When \%\f3GL_REDUCE\fP border mode is in effect,
-the source image must be larger than the final power-of-two size
-by one less than the size of the 1D filter kernel.

-\%\f3glCopyColorTable\fP loads a color table with pixels from the current

-.P
-The screen-aligned pixel rectangle with lower-left corner at (\f2x\fP,\ \f2y\fP)
-having width \f2width\fP and height 1
-is loaded into the color table. If any pixels within
-this region are outside the window that is associated with the GL
-context, the values obtained for those pixels are undefined.
-.P
-The pixels in the rectangle are processed just as if
-\%\f3glReadPixels\fP were called, with \f2internalformat\fP set to RGBA, 
-but processing stops after the final conversion to RGBA.
-.P
-The four scale parameters and the four bias parameters that are defined
-for the table are then used to scale and bias the R, G, B, and A components
-of each pixel. The scale and bias parameters are set by calling
-\%\f3glColorTableParameter\fP.
-.P
-Next, the R, G, B, and A values are clamped to the range [0,1].
-Each pixel is then converted to the internal  specified by
-\f2internalformat\fP. This conversion simply maps the component values of the pixel (R, G, B,
-and A) to the values included in the internal  (red, green, blue,
-alpha, luminance, and intensity).  The mapping is as follows:

-Finally, the red, green, blue, alpha, luminance, and/or intensity components of

-\%\f3glCopyConvolutionFilter1D\fP defines a one-dimensional convolution filter kernel with pixels
-from the current \%\f3GL_READ_BUFFER\fP (rather than from main memory, 
-as is the case for \%\f3glConvolutionFilter1D\fP).
-.sp
-The screen-aligned pixel rectangle with lower-left corner at (\f2x\fP,\ \f2y\fP),
-width \f2width\fP and height 1 is used to define
-the convolution filter.  If any pixels within this region are 
-outside the window that is associated with the GL context, the 
-values obtained for those pixels are undefined.
-.sp
-The pixels in the rectangle are processed exactly as if \%\f3glReadPixels\fP 
-had been called with \f2format\fP
-set to RGBA, but the process stops just before final conversion.  
-The R, G, B, and A components of each pixel are next scaled by the four
-1D \%\f3GL_CONVOLUTION_FILTER_SCALE\fP parameters and biased by the
-four 1D \%\f3GL_CONVOLUTION_FILTER_BIAS\fP parameters.
-(The scale and bias parameters are set by \%\f3glConvolutionParameter\fP
-using the \%\f3GL_CONVOLUTION_1D\fP target and the names
-\%\f3GL_CONVOLUTION_FILTER_SCALE\fP and \%\f3GL_CONVOLUTION_FILTER_BIAS\fP.
-The parameters themselves are vectors of four values that are applied to red,
-green, blue, and alpha, in that order.)
-The R, G, B, and A values are not clamped to [0,1] at any time during this
-process.
-.sp
-Each pixel is then converted to the internal  specified by
-\f2internalformat\fP.
-This conversion simply maps the component values of the pixel (R, G, B,
-and A) to the values included in the internal  (red, green, blue,
-alpha, luminance, and intensity).  The mapping is as follows:

-.SH DESCRIPTION
-\%\f3glCopyPixels\fP copies a screen-aligned rectangle of pixels
-from the specified frame buffer location to a region relative to the
-current raster position.
-Its operation is well defined only if the entire pixel source region
-is within the exposed portion of the window.
-Results of copies from outside the window,
-or from regions of the window that are not exposed,
-are hardware dependent and undefined.
-.P
-\f2x\fP and \f2y\fP specify the window coordinates of
-the lower left corner of the rectangular region to be copied.
-\f2width\fP and \f2height\fP specify the dimensions of the
-rectangular region to be copied.
-Both \f2width\fP and \f2height\fP must not be negative.
-.P
-Several parameters control the processing of the pixel data
-while it is being copied.
-These parameters are set with three commands:
-\%\f3glPixelTransfer\fP,
-\%\f3glPixelMap\fP, and
-\%\f3glPixelZoom\fP.
-This reference page describes the effects on \%\f3glCopyPixels\fP of most,
-but not all, of the parameters specified by these three commands.
-.P
-\%\f3glCopyPixels\fP copies values from each pixel with the lower left-hand corner at
-(\f2x\fP + $i$, \f2y\fP + $j$) for 0 \(<= $i$ < \f2width\fP
-and 0 \(<= $j$ < \f2height\fP.
-This pixel is said to be the $i$th pixel in the $j$th row. 
-Pixels are copied in row order from the lowest to the highest row,
-left to right in each row.
-.P
-\f2type\fP specifies whether color, depth, or stencil data is to be copied.
-The details of the transfer for each data type are as follows:
-.TP 15
-\%\f3GL_COLOR\fP
-Indices or RGBA colors are read from the buffer currently specified as the
-read source buffer (see \%\f3glReadBuffer\fP).
-If the GL is in color index mode,
-each index that is read from this buffer is converted
-to a fixed-point  with an unspecified
-number of bits to the right of the binary point.
-Each index is then shifted left by \%\f3GL_INDEX_SHIFT\fP bits,
-and added to \%\f3GL_INDEX_OFFSET\fP.
-If \%\f3GL_INDEX_SHIFT\fP is negative,
-the shift is to the right.
-In either case, zero bits fill otherwise unspecified bit locations in the
-result.
-If \%\f3GL_MAP_COLOR\fP is true,
-the index is replaced with the value that it references in lookup table
-\%\f3GL_PIXEL_MAP_I_TO_I\fP.
-Whether the lookup replacement of the index is done or not,
-the integer part of the index is then ANDed with $2 sup b -1$,
-where $b$ is the number of bits in a color index buffer.
-.IP
-If the GL is in RGBA mode,
-the red, green, blue, and alpha components of each pixel that is read
-are converted to an internal floating-point  with unspecified
-precision.
-The conversion maps the largest representable component value to 1.0,
-and component value 0 to 0.0.
-The resulting floating-point color values are then multiplied
-by \%\f3GL_c_SCALE\fP and added to \%\f3GL_c_BIAS\fP,
-where \f2c\fP is RED, GREEN, BLUE, and ALPHA 
-for the respective color components.
-The results are clamped to the range [0,1].
-If \%\f3GL_MAP_COLOR\fP is true,
-each color component is scaled by the size of lookup table
-\%\f3GL_PIXEL_MAP_c_TO_c\fP,
-then replaced by the value that it references in that table.
-\f2c\fP is R, G, B, or A.
-.IP
-If the \%\f3GL_ARB_imaging\fP extension is supported, the color values may
-be 
-additionally processed by color-table lookups, color-matrix
-transformations, and convolution filters.
-.IP
-The GL then converts the resulting indices or RGBA colors to fragments
-by attaching the current raster position \f2z\fP coordinate and
-texture coordinates to each pixel,
-then assigning window coordinates
-($x sub r ~+~ i , y sub r ~+~ j$),
-where ($x sub r , y sub r$) is the current raster position,
-and the pixel was the $i$th pixel in the $j$th row.
-These pixel fragments are then treated just like the fragments generated by
-rasterizing points, lines, or polygons.
-Texture mapping,
-fog,
-and all the fragment operations are applied before the fragments are written
-to the frame buffer.
-.TP
-\%\f3GL_DEPTH\fP
-Depth values are read from the depth buffer and
-converted directly to an internal floating-point 
-with unspecified precision.
-The resulting floating-point depth value is then multiplied
-by \%\f3GL_DEPTH_SCALE\fP and added to \%\f3GL_DEPTH_BIAS\fP.
-The result is clamped to the range [0,1].
-.IP
-The GL then converts the resulting depth components to fragments
-by attaching the current raster position color or color index and
-texture coordinates to each pixel,
-then assigning window coordinates
-($x sub r ~+~ i , y sub r ~+~ j$),
-where ($x sub r , y sub r$) is the current raster position,
-and the pixel was the $i$th pixel in the $j$th row.
-These pixel fragments are then treated just like the fragments generated by
-rasterizing points, lines, or polygons.
-Texture mapping,
-fog,
-and all the fragment operations are applied before the fragments are written
-to the frame buffer.
-.TP
-\%\f3GL_STENCIL\fP
-Stencil indices are read from the stencil buffer and
-converted to an internal fixed-point 
-with an unspecified number of bits to the right of the binary point.
-Each fixed-point index is then shifted left by \%\f3GL_INDEX_SHIFT\fP bits,
-and added to \%\f3GL_INDEX_OFFSET\fP.
-If \%\f3GL_INDEX_SHIFT\fP is negative,
-the shift is to the right.
-In either case, zero bits fill otherwise unspecified bit locations in the
-result.
-If \%\f3GL_MAP_STENCIL\fP is true,
-the index is replaced with the value that it references in lookup table
-\%\f3GL_PIXEL_MAP_S_TO_S\fP.
-Whether the lookup replacement of the index is done or not,
-the integer part of the index is then ANDed with $2 sup b -1$,
-where $b$ is the number of bits in the stencil buffer.
-The resulting stencil indices are then written to the stencil buffer
-such that the index read from the $i$th location of the $j$th row
-is written to location
-($x sub r ~+~ i , y sub r ~+~ j$),
-where ($x sub r , y sub r$) is the current raster position.
-Only the pixel ownership test,
-the scissor test,
-and the stencil writemask affect these write operations.
-.P
-The rasterization described thus far assumes pixel zoom factors of 1.0.
-If 
-.br
-\%\f3glPixelZoom\fP is used to change the $x$ and $y$ pixel zoom factors,
-pixels are converted to fragments as follows.
-If ($x sub r$, $y sub r$) is the current raster position,
-and a given pixel is in the $i$th location in the $j$th row of the source
-pixel rectangle,
-then fragments are generated for pixels whose centers are in the rectangle
-with corners at

-\f2internalformat\fP specifies the internal  of the texture array.
-.P
-The pixels in the row are processed exactly as if
-\%\f3glCopyPixels\fP had been called, but the process stops just before
-final conversion.
-At this point all pixel component values are clamped to the range [0,\ 1]
-and then converted to the texture's internal  for storage in the texel
-array.
-.P
-Pixel ordering is such that lower $x$ screen coordinates correspond to 
-lower texture coordinates.
-.P
-If any of the pixels within the specified row of the current
-\%\f3GL_READ_BUFFER\fP are outside the window associated with the current
-rendering context, then the values obtained for those pixels are undefined.
-.SH NOTES

-.SH DESCRIPTION
-\%\f3glCopyTexSubImage3D\fP replaces a rectangular portion of a three-dimensional
-texture image with pixels from the current \%\f3GL_READ_BUFFER\fP (rather
-than from main memory, as is the case for \%\f3glTexSubImage3D\fP).
-.P
-The screen-aligned pixel rectangle with lower left corner at
-(\f2x\fP,\ \f2y\fP) and with
-width \f2width\fP and height \f2height\fP replaces the portion of the
-texture array with x indices \f2xoffset\fP through \f2xoffset\fP$~+~$\f2width\fP$~-~$1,
-inclusive, and y indices \f2yoffset\fP through \f2yoffset\fP$~+~$\f2height\fP$~-~$1,
-inclusive, at z index \f2zoffset\fP and at the mipmap level specified by \f2level\fP.
-.P
-The pixels in the rectangle are processed exactly as if
-\%\f3glCopyPixels\fP had been called, but the process stops just before
-final conversion.
-At this point, all pixel component values are clamped to the range [0,\ 1]
-and then converted to the texture's internal  for storage in the texel
-array.
-.P
-The destination rectangle in the texture array may not include any texels
-outside the texture array as it was originally specified.
-It is not an error to specify a subtexture with zero width or height, but
-such a specification has no effect.
-.P
-If any of the pixels within the specified rectangle of the current
-\%\f3GL_READ_BUFFER\fP are outside the read window associated with the current
-rendering context, then the values obtained for those pixels are undefined.
-.P
-No change is made to the \f2internalformat\fP, \f2width\fP,
-\f2height\fP, \f2depth\fP, or \f2border\fP parameters of the specified texture
-array or to texel values outside the specified subregion.
-.SH NOTES
-\%\f3glCopyTexSubImage3D\fP is available only if the GL version is 1.2 or greater. 
-.P
-Texturing has no effect in color index mode.
-.P
-\%\f3glPixelStore\fP and \%\f3glPixelTransfer\fP modes affect texture images
-in exactly the way they affect \%\f3glDrawPixels\fP.
-.P
-When the \%\f3GL_ARB_imaging\fP extension is supported, the RGBA components
-copied from the framebuffer may be processed by the imaging pipeline, as 
-if they were a two-dimensional texture.  See \%\f3glTexImage2D\fP for

-\%\f3glDrawArrays\fP specifies multiple geometric primitives

-.br
-\%\f3glRasterPos\fP to set the current raster position; use

-to determine if the specified raster position is valid, and 
-\%\f3glGet\fP with argument \%\f3GL_CURRENT_RASTER_POSITION\fP
-to query the raster position.
-.P
-Several parameters define the encoding of pixel data in memory
-and control the processing of the pixel data
-before it is placed in the frame buffer.
-These parameters are set with four commands:
-\%\f3glPixelStore\fP,
-\%\f3glPixelTransfer\fP,
-\%\f3glPixelMap\fP, and \%\f3glPixelZoom\fP.
-This reference page describes the effects on \%\f3glDrawPixels\fP of many,
-but not all, of the parameters specified by these four commands.
-.P
-Data is read from \f2pixels\fP as a sequence of signed or unsigned bytes,
-signed or unsigned shorts, signed or unsigned integers, or
-single-precision floating-point values, depending on \f2type\fP.  
-When \f2type\fP is one of \%\f3GL_UNSIGNED_BYTE\fP, \%\f3GL_BYTE\fP,
-\%\f3GL_UNSIGNED_SHORT\fP, \%\f3GL_SHORT\fP, \%\f3GL_UNSIGNED_INT\fP,
-\%\f3GL_INT\fP, or \%\f3GL_FLOAT\fP each of these bytes, shorts, integers, or
-floating-point values is interpreted as one color or depth component, or
-one index, depending on \f2format\fP.
-When \f2type\fP is one of \%\f3GL_UNSIGNED_BYTE_3_3_2\fP,
-\%\f3GL_UNSIGNED_SHORT_5_6_5\fP, \%\f3GL_UNSIGNED_SHORT_4_4_4_4\fP,
-\%\f3GL_UNSIGNED_SHORT_5_5_5_1\fP, \%\f3GL_UNSIGNED_INT_8_8_8_8\fP,
-\%\f3GL_UNSIGNED_INT_10_10_10_2\fP, each unsigned value is interpreted as
-containing all the components for a single pixel, with the color
-components arranged according to \f2format\fP.
-When \f2type\fP is one of \%\f3GL_UNSIGNED_BYTE_2_3_3_REV\fP,
-\%\f3GL_UNSIGNED_SHORT_5_6_5_REV\fP, \%\f3GL_UNSIGNED_SHORT_4_4_4_4_REV\fP,

-\%\f3GL_UNSIGNED_INT_2_10_10_10_REV\fP, each unsigned value is interpreted
-as containing all color components, specified by \f2format\fP, for a single
-pixel in a reversed order. Indices are always treated individually.
-Color components are treated as groups of one, two, three, or four
-values, again based on \f2format\fP. Both individual indices and groups of
-components are referred to as pixels.
-If \f2type\fP is \%\f3GL_BITMAP\fP, the data must be unsigned bytes, and
-\f2format\fP must be either \%\f3GL_COLOR_INDEX\fP or \%\f3GL_STENCIL_INDEX\fP.
-Each unsigned byte is treated as eight 1-bit pixels, with bit ordering
-determined by \%\f3GL_UNPACK_LSB_FIRST\fP (see \%\f3glPixelStore\fP).
-.P
-\f2width\fP$~ times ~$\f2height\fP pixels are read from memory,
-starting at location \f2pixels\fP.
-By default, these pixels are taken from adjacent memory locations,
-except that after all \f2width\fP pixels are read,
-the read pointer is advanced to the next four-byte boundary.
-The four-byte row alignment is specified by \%\f3glPixelStore\fP with
-argument \%\f3GL_UNPACK_ALIGNMENT\fP,
-and it can be set to one, two, four, or eight bytes.
-Other pixel store parameters specify different read pointer advancements,
-both before the first pixel is read
-and after all \f2width\fP pixels are read.
-See the \%\f3glPixelStore\fP reference page for details on these options.
-.P
-The \f2width\fP$~ times ~$\f2height\fP pixels that are read from memory are
-each operated on in the same way,
-based on the values of several parameters specified by \%\f3glPixelTransfer\fP
-and \%\f3glPixelMap\fP.
-The details of these operations,
-as well as the target buffer into which the pixels are drawn,
-are specific to the  of the pixels,
-as specified by \f2format\fP.
-\f2format\fP can assume one of 13 symbolic values:
-.TP 10
-\%\f3GL_COLOR_INDEX\fP
-Each pixel is a single value,
-a color index.
-It is converted to fixed-point ,
-with an unspecified number of bits to the right of the binary point,
-regardless of the memory data type.
-Floating-point values convert to true fixed-point values.
-Signed and unsigned integer data is converted with all fraction bits
-set to 0.
-Bitmap data convert to either 0 or 1.
-.IP
-Each fixed-point index is then shifted left by \%\f3GL_INDEX_SHIFT\fP bits
-and added to \%\f3GL_INDEX_OFFSET\fP.
-If \%\f3GL_INDEX_SHIFT\fP is negative,
-the shift is to the right.
-In either case, zero bits fill otherwise unspecified bit locations in the
-result.
-.IP
-If the GL is in RGBA mode,
-the resulting index is converted to an RGBA pixel 
-with the help of the \%\f3GL_PIXEL_MAP_I_TO_R\fP, 
-\%\f3GL_PIXEL_MAP_I_TO_G\fP,
-\%\f3GL_PIXEL_MAP_I_TO_B\fP,
-and \%\f3GL_PIXEL_MAP_I_TO_A\fP tables.
-If the GL is in color index mode,
-and if \%\f3GL_MAP_COLOR\fP is true,
-the index is replaced with the value that it references in lookup table
-\%\f3GL_PIXEL_MAP_I_TO_I\fP.
-Whether the lookup replacement of the index is done or not,
-the integer part of the index is then ANDed with $2 sup b -1$,
-where $b$ is the number of bits in a color index buffer.
-.BP
-.IP
-The GL then converts the resulting indices or RGBA colors to fragments
-by attaching the current raster position \f2z\fP coordinate and
-texture coordinates to each pixel,
-then assigning $x$ and $y$ window coordinates to the $n$th fragment such that
-.sp

-.ce 0
-.sp
-.RE
-.IP
-where ($x sub r , y sub r$) is the current raster position.
-These pixel fragments are then treated just like the fragments generated by
-rasterizing points, lines, or polygons.
-Texture mapping,
-fog,
-and all the fragment operations are applied before the fragments are written
-to the frame buffer.
-.TP
-\%\f3GL_STENCIL_INDEX\fP
-Each pixel is a single value,
-a stencil index.
-It is converted to fixed-point ,
-with an unspecified number of bits to the right of the binary point,
-regardless of the memory data type.
-Floating-point values convert to true fixed-point values.
-Signed and unsigned integer data is converted with all fraction bits
-set to 0.
-Bitmap data convert to either 0 or 1.
-.IP
-Each fixed-point index is then shifted left by \%\f3GL_INDEX_SHIFT\fP bits,
-and added to \%\f3GL_INDEX_OFFSET\fP.
-If \%\f3GL_INDEX_SHIFT\fP is negative,
-the shift is to the right.
-In either case, zero bits fill otherwise unspecified bit locations in the
-result.
-If \%\f3GL_MAP_STENCIL\fP is true,
-the index is replaced with the value that it references in lookup table
-\%\f3GL_PIXEL_MAP_S_TO_S\fP.
-Whether the lookup replacement of the index is done or not,
-the integer part of the index is then ANDed with $2 sup b -1$,
-where $b$ is the number of bits in the stencil buffer.
-The resulting stencil indices are then written to the stencil buffer
-such that the $n$th index is written to location
-.P
-.RS
-.ce
-$x sub n ~=~ x sub r ~+~ n ~ roman mod ~ "width"$ 
-.sp
-.ce
-$y sub n ~=~ y sub r ~+~ \(lf ~ n / "width" ~ \(rf$
-.fi
-.sp
-.RE
-.IP
-where ($x sub r , y sub r$) is the current raster position.
-Only the pixel ownership test,
-the scissor test,
-and the stencil writemask affect these write operations.
-.TP
-\%\f3GL_DEPTH_COMPONENT\fP
-Each pixel is a single-depth component.
-Floating-point data is converted directly to an internal floating-point

-.SH DESCRIPTION
-\%\f3glDrawRangeElements\fP is a restricted form of \%\f3glDrawElements\fP. \f2mode\fP, \f2start\fP, \f2end\fP,
-and \f2count\fP match the corresponding arguments to \%\f3glDrawElements\fP, with
-the additional constraint that all values in the arrays \f2count\fP must lie
-between \f2start\fP and \f2end\fP, inclusive.
-.P
-Implementations denote recommended maximum amounts of vertex and
-.br
-index data,
-which may be queried by calling \%\f3glGet\fP with argument 
-\%\f3GL_MAX_ELEMENTS_VERTICES\fP and \%\f3GL_MAX_ELEMENTS_INDICES\fP.
-If $"end" ~-~ "start" ~+~ 1$ is greater than the value of
-\%\f3GL_MAX_ELEMENTS_VERTICES\fP, or if \f2count\fP is greater than the value of
-\%\f3GL_MAX_ELEMENTS_INDICES\fP, then the call may operate at reduced
-performance.  There is no requirement that all vertices in the range
-[\f2start\fP,\ \f2end\fP] be referenced.  However, the implementation may
-partially process unused vertices, reducing performance from what could 
-be achieved with an optimal index set.
-.P
-When \%\f3glDrawRangeElements\fP is called, it uses \f2start\fP sequential elements from an
-enabled array, starting at \f2count\fP to construct a sequence of
-geometric primitives. \f2mode\fP specifies what kind of primitives are
-constructed, and how the array elements construct these primitives. If
-more than one array is enabled, each is used. If
-\%\f3GL_VERTEX_ARRAY\fP is not enabled, no geometric primitives are
-constructed.
-.P
-Vertex attributes that are modified by \%\f3glDrawRangeElements\fP have an
-unspecified value after \%\f3glDrawRangeElements\fP returns. For example, if
-\%\f3GL_COLOR_ARRAY\fP is enabled, the value of the current color is
-undefined after \%\f3glDrawRangeElements\fP executes. Attributes that aren't
-modified maintain their previous values.
-.SH NOTES
-\%\f3glDrawRangeElements\fP is available only if the GL version is 1.2 or greater.
-.P
-\%\f3glDrawRangeElements\fP is included in display lists. If \%\f3glDrawRangeElements\fP is entered into a
-display list, 
-the necessary array data (determined by the array pointers and
-enables) is also 
-entered into the display list. Because the array pointers and
-enables are client-side state, their values affect display lists
-when the lists are created, not when the lists are executed.
-.SH ERRORS
-It is an error for indices to lie outside the range [\f2start\fP,\ \f2end\fP],

-\f2u\fP
-Specifies a pointer to an array containing
-either one or two domain coordinates.
-The first coordinate is $u$.
-The second coordinate is $v$,
-which is present only in \%\f3glEvalCoord2\fP versions.
-.SH DESCRIPTION
-\%\f3glEvalCoord1\fP evaluates enabled one-dimensional maps at argument
-\f2u\fP.
-\%\f3glEvalCoord2\fP does the same for two-dimensional maps using
-two domain values,
-\f2u\fP and \f2v\fP.
-To define a map, call \%\f3glMap1\fP and \%\f3glMap2\fP; to enable and
-disable it, call \%\f3glEnable\fP and \%\f3glDisable\fP.
-.P
-When one of the \%\f3glEvalCoord\fP commands is issued,
-all currently enabled maps of the indicated dimension are evaluated.
-Then,
-for each enabled map,
-it is as if the corresponding GL command had been issued with the
-computed value.
-That is,
-if \%\f3GL_MAP1_INDEX\fP or
-\%\f3GL_MAP2_INDEX\fP is enabled,
-a \%\f3glIndex\fP command is simulated.
-If \%\f3GL_MAP1_COLOR_4\fP or
-\%\f3GL_MAP2_COLOR_4\fP is enabled,
-a \%\f3glColor\fP command is simulated.
-If \%\f3GL_MAP1_NORMAL\fP or \%\f3GL_MAP2_NORMAL\fP is enabled,
-a normal vector is produced,
-and if any of
-\%\f3GL_MAP1_TEXTURE_COORD_1\fP,
-\%\f3GL_MAP1_TEXTURE_COORD_2\fP,
-\%\f3GL_MAP1_TEXTURE_COORD_3\fP, 
-\%\f3GL_MAP1_TEXTURE_COORD_4\fP,
-\%\f3GL_MAP2_TEXTURE_COORD_1\fP,
-\%\f3GL_MAP2_TEXTURE_COORD_2\fP,
-\%\f3GL_MAP2_TEXTURE_COORD_3\fP, or
-\%\f3GL_MAP2_TEXTURE_COORD_4\fP is enabled, then an appropriate \%\f3glTexCoord\fP command is simulated.
-.P
-For color,
-color index,
-normal,
-and texture coordinates the GL uses evaluated values instead of current values for those evaluations
-that are enabled,
-and current values otherwise,
-However,
-the evaluated values do not update the current values.
-Thus, if \%\f3glVertex\fP commands are interspersed with \%\f3glEvalCoord\fP
-commands, the color,
-normal,
-and texture coordinates associated with the \%\f3glVertex\fP commands are not
-affected by the values generated by the \%\f3glEvalCoord\fP commands,
-but only by the most recent
-\%\f3glColor\fP,
-\%\f3glIndex\fP,
-\%\f3glNormal\fP, and
-\%\f3glTexCoord\fP commands.
-.P
-No commands are issued for maps that are not enabled.
-If more than one texture evaluation is enabled for a particular dimension
-(for example, \%\f3GL_MAP2_TEXTURE_COORD_1\fP and
-\%\f3GL_MAP2_TEXTURE_COORD_2\fP),
-then only the evaluation of the map that produces the larger
-number of coordinates
-(in this case, \%\f3GL_MAP2_TEXTURE_COORD_2\fP)
-is carried out.
-\%\f3GL_MAP1_VERTEX_4\fP overrides \%\f3GL_MAP1_VERTEX_3\fP,
-and
-\%\f3GL_MAP2_VERTEX_4\fP overrides \%\f3GL_MAP2_VERTEX_3\fP,
-in the same manner.
-If neither a three- nor a four-component vertex map is enabled for the
-specified dimension,
-the \%\f3glEvalCoord\fP command is ignored.
-.P
-If you have enabled automatic normal generation,
-by calling \%\f3glEnable\fP with argument \%\f3GL_AUTO_NORMAL\fP,
-\%\f3glEvalCoord2\fP generates surface normals analytically,
-regardless of the contents or enabling of the \%\f3GL_MAP2_NORMAL\fP map.
-Let
-.sp
-.ce
-.EQ
-bold m ~=~ {partial bold p} over {partial u} ~times~

-.ce 0

-Then the generated normal $ bold n $ is 
-.br
-.ce
-$bold n ~=~ bold m over { || bold m || }$
-.ce 0
-.sp
-.br
-If automatic normal generation is disabled,
-the corresponding normal map \%\f3GL_MAP2_NORMAL\fP,
-if enabled,
-is used to produce a normal.
-If neither automatic normal generation nor a normal map is enabled,

-\f2buffer\fP
-Returns the feedback data.
-.SH DESCRIPTION
-The \%\f3glFeedbackBuffer\fP function controls feedback.
-Feedback, like selection, is a GL mode.
-The mode is selected by calling
-\%\f3glRenderMode\fP with \%\f3GL_FEEDBACK\fP.
-When the GL is in feedback mode,
-no pixels are produced by rasterization.
-Instead, information about primitives that would have been
-rasterized is fed back to the application using the GL.
-.P
-\%\f3glFeedbackBuffer\fP has three arguments:
-\f2buffer\fP is a pointer to an array of floating-point values
-into which feedback information is placed.
-\f2size\fP indicates the size of the array.
-\f2type\fP is a symbolic constant describing the information
-that is fed back for each vertex.
-\%\f3glFeedbackBuffer\fP must be issued before feedback mode is enabled
-(by calling \%\f3glRenderMode\fP with argument \%\f3GL_FEEDBACK\fP).
-Setting \%\f3GL_FEEDBACK\fP without establishing the feedback buffer,
-or calling \%\f3glFeedbackBuffer\fP while the GL is in feedback mode,
-is an error.
-.P
-When \%\f3glRenderMode\fP is called while in feedback mode, it returns the number of entries
-placed in the feedback array, and resets the feedback array pointer to the base
-of the feedback buffer. The returned value never exceeds \f2size\fP. If the feedback
-data required more room than was available in \f2buffer\fP, 
-\%\f3glRenderMode\fP returns a negative value.
-To take the GL out of feedback mode, call
-\%\f3glRenderMode\fP with a parameter value other than \%\f3GL_FEEDBACK\fP.
-.P
-While in feedback mode,
-each primitive, bitmap, or pixel rectangle that would be rasterized
-generates a block of values that are copied into the feedback array.
-If doing so would cause the number of entries to exceed the maximum,
-the block is partially written so as to fill the array
-(if there is any room left at all),
-and an overflow flag is set.
-Each block begins with a code indicating the primitive type,
-followed by values that describe the primitive's vertices and
-associated data.
-Entries are also written for bitmaps and pixel rectangles.
-Feedback occurs after polygon culling and \%\f3glPolygonMode\fP interpretation
-of polygons has taken place,
-so polygons that are culled are not returned in the feedback buffer.
-It can also occur after polygons with more than three edges are broken up
-into triangles,
-if the GL implementation renders polygons by performing this decomposition.
-.P
-The \%\f3glPassThrough\fP command can be used to insert a marker
-into the feedback buffer.
-See \%\f3glPassThrough\fP.
-.P
-Following is the grammar for the blocks of values written
-into the feedback buffer.
-Each primitive is indicated with a unique identifying value
-followed by some number of vertices.
-Polygon entries include an integer value indicating how many vertices follow.
-A vertex is fed back as some number of floating-point values,
-as determined by \f2type\fP.
-Colors are fed back as four values in RGBA mode and one value
-in color index mode.

-
-.SH DESCRIPTION
-\%\f3glGetError\fP returns the value of the error flag.
-Each detectable error is assigned a numeric code and symbolic name.
-When an error occurs,
-the error flag is set to the appropriate error code value.
-No other errors are recorded until \%\f3glGetError\fP is called,
-the error code is returned,
-and the flag is reset to \%\f3GL_NO_ERROR\fP.
-If a call to \%\f3glGetError\fP returns \%\f3GL_NO_ERROR\fP,
-there has been no detectable error since the last call to \%\f3glGetError\fP,
-or since the GL was initialized.
-.P
-To allow for distributed implementations,
-there may be several error flags.
-If any single error flag has recorded an error,
-the value of that flag is returned
-and that flag is reset to \%\f3GL_NO_ERROR\fP
-when \%\f3glGetError\fP is called.
-If more than one flag has recorded an error,
-\%\f3glGetError\fP returns and clears an arbitrary error flag value.
-Thus, \%\f3glGetError\fP should always be called in a loop,
-until it returns \%\f3GL_NO_ERROR\fP,
-if all error flags are to be reset.
-.P
-Initially, all error flags are set to \%\f3GL_NO_ERROR\fP.
-.P
-The following errors are currently defined:
-.TP 30
-\%\f3GL_NO_ERROR\fP
-No error has been recorded.
-The value of this symbolic constant is guaranteed to be 0.
-.TP
-\%\f3GL_INVALID_ENUM\fP
-An unacceptable value is specified for an enumerated argument.
-The offending command is ignored,
-and has no other side effect than to set the error flag.
-.TP
-\%\f3GL_INVALID_VALUE\fP
-A numeric argument is out of range.
-The offending command is ignored,
-and has no other side effect than to set the error flag.
-.TP
-\%\f3GL_INVALID_OPERATION\fP
-The specified operation is not allowed in the current state.
-The offending command is ignored,
-and has no other side effect than to set the error flag.
-.TP
-\%\f3GL_STACK_OVERFLOW\fP
-This command would cause a stack overflow.
-The offending command is ignored,
-and has no other side effect than to set the error flag.
-.TP
-\%\f3GL_STACK_UNDERFLOW\fP
-This command would cause a stack underflow.
-The offending command is ignored,
-and has no other side effect than to set the error flag.
-.TP
-\%\f3GL_OUT_OF_MEMORY\fP
-There is not enough memory left to execute the command.
-The state of the GL is undefined,
-except for the state of the error flags,
-after this error is recorded.
-.TP
-\%\f3GL_TABLE_TOO_LARGE\fP
-The specified table exceeds the implementation's maximum supported table 
-size.  The offending command is ignored, and has no other side effect
-than to set the error flag.
-.P
-When an error flag is set,
-results of a GL operation are undefined only if \%\f3GL_OUT_OF_MEMORY\fP
-has occurred.
-In all other cases,
-the command generating the error is ignored and has no effect on the GL state
-or frame buffer contents.
-If the generating command returns a value, it returns 0.  
-If \%\f3glGetError\fP itself generates an error, it returns 0. 
-.SH NOTES
-\%\f3GL_TABLE_TOO_LARGE\fP was introduced in GL version 1.2.
-.SH ERRORS
-\%\f3GL_INVALID_OPERATION\fP is generated if \%\f3glGetError\fP
-is executed between the execution of \%\f3glBegin\fP
-and the corresponding execution of \%\f3glEnd\fP.
-In this case \%\f3glGetError\fP returns 0.

-the nearest integer. The initial value is 0. 
-.TP
-\%\f3GL_SPOT_CUTOFF\fP
-\f2params\fP returns a single integer or floating-point value representing the

-The client and server may support different versions or extensions.
-\%\f3glGetString\fP always returns a compatible version number or list of extensions.

-.SH ERRORS
-\%\f3GL_INVALID_ENUM\fP is generated if \f2name\fP is not an accepted value.

-\f2pixels\fP
-Returns the texture image.
-Should be a pointer to an array of the type specified by \f2type\fP.
-.SH DESCRIPTION
-\%\f3glGetTexImage\fP returns a texture image into \f2pixels\fP.
-\f2target\fP specifies whether the desired texture image is one specified by
-\%\f3glTexImage1D\fP (\%\f3GL_TEXTURE_1D\fP),
-\%\f3glTexImage2D\fP (\%\f3GL_TEXTURE_2D\fP), or
-\%\f3glTexImage3D\fP (\%\f3GL_TEXTURE_3D\fP).
-\f2level\fP specifies the level-of-detail number of the desired image.
-\f2format\fP and \f2type\fP specify the  and type of the desired image array.
-See the reference pages \%\f3glTexImage1D\fP and \%\f3glDrawPixels\fP
-for a description of the acceptable values for the \f2format\fP and \f2type\fP
-parameters, respectively.
-.P
-To understand the operation of \%\f3glGetTexImage\fP, consider the selected internal
-four-component texture image to be an RGBA color buffer the size of the image.
-The semantics of \%\f3glGetTexImage\fP are then identical to those of \%\f3glReadPixels\fP,
-with the exception that no pixel transfer operations are performed,
-when called with the same \f2format\fP and \f2type\fP,
-with \f2x\fP and \f2y\fP set to 0,
-\f2width\fP set to the width of the texture image
-(including border if one was specified),
-and \f2height\fP set to 1 for 1D images,
-or to the height of the texture image
-(including border if one was specified)
-for 2D images.
-.BP
-Because the internal texture image is an RGBA image,
-pixel formats \%\f3GL_COLOR_INDEX\fP,
-\%\f3GL_STENCIL_INDEX\fP,
-and \%\f3GL_DEPTH_COMPONENT\fP are not accepted,
-and pixel type \%\f3GL_BITMAP\fP is not accepted.
-.P
-If the selected texture image does not contain four components,
-the following mappings are applied.
-Single-component textures are treated as RGBA buffers with red set
-to the single-component value,
-green set to 0,  blue set to 0, and alpha set to 1.
-Two-component textures are treated as RGBA buffers with red set to
-the value of component zero,
-alpha set to the value of component one,
-and green and blue set to 0.
-Finally,
-three-component textures are treated as RGBA buffers with red set to
-component zero,
-green set to component one,
-blue set to component two,
-and alpha set to 1.
-.P
-To determine the required size of \f2pixels\fP,
-use \%\f3glGetTexLevelParameter\fP to determine the dimensions of the
-internal texture image,
-then scale the required number of pixels by the storage required for
-each pixel,
-based on \f2format\fP and \f2type\fP.
-Be sure to take the pixel storage parameters into account,
-especially \%\f3GL_PACK_ALIGNMENT\fP.
-.SH NOTES
-If an error is generated,
-no change is made to the contents of \f2pixels\fP.
-.P
-When the \%\f3GL_ARB_multitexture\fP extension is supported, \%\f3glGetTexImage\fP returns
-the texture image for the active texture unit.

-.SH DESCRIPTION
-\%\f3glGetTexLevelParameter\fP returns in \f2params\fP texture parameter values for a specific 
-level-of-detail value,

-\f2target\fP defines the target texture,
-either \%\f3GL_TEXTURE_1D\fP, \%\f3GL_TEXTURE_2D\fP, \%\f3GL_TEXTURE_3D\fP,
-\%\f3GL_PROXY_TEXTURE_1D\fP,

-.BR
-.P
-\%\f3GL_MAX_TEXTURE_SIZE\fP, and \%\f3GL_MAX_3D_TEXTURE_SIZE\fP are not really
-descriptive enough.
-It has to report the largest square texture image that can be

-easily fit in texture memory. 
-The proxy targets allow the user to more accurately query
-whether the GL can accommodate a texture of a given configuration.
-If the texture cannot be accommodated, the texture state variables, which
-may be queried with \%\f3glGetTexLevelParameter\fP, are set to 0.  If the texture can be accommodated,
-the texture state values will be set as they would be set for a
-non-proxy target.

-\f2pname\fP specifies the texture parameter whose value or values
-will be returned.
-.P

-If \%\f3GL_FALSE\fP, pixels will proceed to the minmax process after

-.SH DESCRIPTION
-When \%\f3GL_HISTOGRAM\fP is enabled, RGBA color components are converted to
-histogram table indices by clamping to the range [0,1], multiplying by
-the width of the histogram table, and rounding to the nearest integer.
-The table entries selected by the RGBA indices are then incremented.
-(If the internal  of the histogram table includes luminance, then
-the index derived from the R color component determines the luminance
-table entry to be incremented.)  If a histogram table entry is incremented
-beyond its maximum value, then its value becomes undefined.  (This is
-not an error.)
-.PP
-Histogramming is performed only for RGBA pixels (though these may
-be specified originally as color indices and converted to RGBA by
-index table lookup).
-Histogramming is enabled with \%\f3glEnable\fP and disabled with \%\f3glDisable\fP.
-.PP
-When \f2target\fP is \%\f3GL_HISTOGRAM\fP, \%\f3glHistogram\fP redefines the current
-histogram table to have \f2width\fP entries of the  specified by
-\f2internalformat\fP.
-The entries are indexed 0 through $"width" ~-~ 1$, and
-all entries are initialized to zero.
-The values in the previous histogram table, if any, are lost.
-If \f2sink\fP is \%\f3GL_TRUE\fP, then pixels are discarded after histogramming;
-no further processing of the pixels takes place, and no drawing,
-texture loading, or pixel readback will result.
-.PP
-When \f2target\fP is \%\f3GL_PROXY_HISTOGRAM\fP, \%\f3glHistogram\fP computes all
-state information as if the histogram table were to be redefined,
-but does not actually define the new table.
-If the requested histogram table is too large to be supported, then the
-state information will be set to zero.
-This provides a way to determine if a histogram table with the given
-parameters can be supported.

-arrays whose elements are part of a larger aggregate array element.
-For some implementations, this is more efficient than specifying the arrays

-If \f2stride\fP is 0, the aggregate elements are stored consecutively.
-Otherwise, \f2stride\fP bytes occur between the beginning of one

-element.
-.P
-\f2format\fP serves as a ``key''
-describing the extraction of individual arrays from the aggregate array.
-If \f2format\fP contains a T, then texture coordinates are 
-extracted from the interleaved array.  If C is present, color values
-are extracted. If N is present, normal coordinates are extracted.
-Vertex coordinates are always extracted.
-.P
-The digits 2, 3, and 4 denote how many values are extracted.
-F indicates that values are extracted as floating-point values.
-Colors may also be extracted as 4 unsigned bytes if 4UB follows the
-C.  If a color is extracted as 4 unsigned bytes, the vertex 
-array element which follows is located at the first possible 
-floating-point aligned address.

-\f2light\fP names the light and is a symbolic name of the form \%\f3GL_LIGHT\fP$i$,
-where 0 \(<= i < \%\f3GL_MAX_LIGHTS\fP.
-\f2pname\fP specifies one of ten light source parameters,
-again by symbolic name.
-\f2params\fP is either a single value or a pointer to an array that contains
-the new values.
-.P
-To enable and disable lighting calculation, call \%\f3glEnable\fP
-and \%\f3glDisable\fP with argument \%\f3GL_LIGHTING\fP. Lighting is
-initially disabled.
-When it is enabled,
-light sources that are enabled contribute to the lighting calculation.
-Light source $i$ is enabled and disabled using \%\f3glEnable\fP and
-\%\f3glDisable\fP with argument \%\f3GL_LIGHT\fP$i$. 
-.P
-The ten light parameters are as follows:
-.TP 20
-\%\f3GL_AMBIENT\fP
-\f2params\fP contains four integer or floating-point values that specify
-the ambient RGBA intensity of the light.
-Integer values are mapped linearly such that the most positive representable
-value maps to 1.0,
-and the most negative representable value maps to \-1.0.
-Floating-point values are mapped directly.
-Neither integer nor floating-point values are clamped.
-The initial ambient light intensity is (0, 0, 0, 1).
-.TP
-\%\f3GL_DIFFUSE\fP
-\f2params\fP contains four integer or floating-point values that specify
-the diffuse RGBA intensity of the light.
-Integer values are mapped linearly such that the most positive representable
-value maps to 1.0,
-and the most negative representable value maps to \-1.0.
-Floating-point values are mapped directly.
-Neither integer nor floating-point values are clamped.
-The initial value
-for \%\f3GL_LIGHT0\fP is (1, 1, 1, 1); for other lights, the
-initial value is (0, 0, 0, 0). 
-.TP
-\%\f3GL_SPECULAR\fP
-\f2params\fP contains four integer or floating-point values that specify
-the specular RGBA intensity of the light.
-Integer values are mapped linearly such that the most positive representable
-value maps to 1.0,
-and the most negative representable value maps to \-1.0.
-Floating-point values are mapped directly.
-Neither integer nor floating-point values are clamped.
-The initial value
-for \%\f3GL_LIGHT0\fP is (1, 1, 1, 1); for other lights, the
-initial value is (0, 0, 0, 0). 
-.TP
-\%\f3GL_POSITION\fP
-\f2params\fP contains four integer or floating-point values that specify
-the position of the light in homogeneous object coordinates.
-Both integer and floating-point values are mapped directly.
-Neither integer nor floating-point values are clamped.
-.IP
-The position is transformed by the modelview matrix when
-\%\f3glLight\fP is called (just as if it were a point),
-and it is stored in eye coordinates.
-If the $w$ component of the position is 0,
-the light is treated as a directional source.
-Diffuse and specular lighting calculations take the light's direction,
-but not its actual position,
-into account,
-and attenuation is disabled.
-Otherwise,
-diffuse and specular lighting calculations are based on the actual location
-of the light in eye coordinates,
-and attenuation is enabled.
-The initial position is (0, 0, 1, 0);
-thus, the initial light source is directional,
-parallel to, and in the direction of the $-z$ axis.
-.TP
-\%\f3GL_SPOT_DIRECTION\fP
-\f2params\fP contains three integer or floating-point values that specify
-the direction of the light in homogeneous object coordinates.
-Both integer and floating-point values are mapped directly.
-Neither integer nor floating-point values are clamped.
-.IP
-The spot direction is transformed by the inverse of the modelview matrix when
-\%\f3glLight\fP is called (just as if it were a normal),
-and it is stored in eye coordinates.
-It is significant only when \%\f3GL_SPOT_CUTOFF\fP is not 180,
-which it is initially.
-The initial direction is (0, 0, \-1).
-.TP
-\%\f3GL_SPOT_EXPONENT\fP
-\f2params\fP is a single integer or floating-point value that specifies
-the intensity distribution of the light.
-Integer and floating-point values are mapped directly.
-Only values in the range [0,128] are accepted.
-.IP
-Effective light intensity is attenuated by the cosine of the angle between
-the direction of the light and the direction from the light to the vertex
-being lighted,
-raised to the power of the spot exponent.
-Thus, higher spot exponents result in a more focused light source,
-regardless of the spot cutoff angle (see \%\f3GL_SPOT_CUTOFF\fP, next paragraph).
-The initial spot exponent is 0,
-resulting in uniform light distribution.
-.TP
-\%\f3GL_SPOT_CUTOFF\fP
-\f2params\fP is a single integer or floating-point value that specifies
-the maximum spread angle of a light source.
-Integer and floating-point values are mapped directly.
-Only values in the range [0,90] and the special value 180
-are accepted.
-If the angle between the direction of the light and the direction from the
-light to the vertex being lighted is greater than the spot cutoff angle,
-the light is completely masked.
-.BP
-Otherwise, its intensity is controlled by the spot exponent and the
-attenuation factors.
-The initial spot cutoff is 180,
-resulting in uniform light distribution.
-.TP
-\%\f3GL_CONSTANT_ATTENUATION\fP
-.TP
-\%\f3GL_LINEAR_ATTENUATION \fP
-.TP
-\%\f3GL_QUADRATIC_ATTENUATION\fP
-\f2params\fP is a single integer or floating-point value that specifies
-one of the three light attenuation factors.
-Integer and floating-point values are mapped directly.
-Only nonnegative values are accepted.
-If the light is positional,
-rather than directional,
-its intensity is attenuated by the reciprocal of the sum of the constant
-factor, the linear factor times the distance between the light
-and the vertex being lighted,
-and the quadratic factor times the square of the same distance.
-The initial attenuation factors are (1, 0, 0),
-resulting in no attenuation.
-.SH NOTES
-It is always the case that \%\f3GL_LIGHT\fP$i$ = \%\f3GL_LIGHT0\fP + $i$.
-.SH ERRORS
-\%\f3GL_INVALID_ENUM\fP is generated if either \f2light\fP or \f2pname\fP
-is not an accepted value.

-\%\f3GL_INVALID_VALUE\fP is generated if a spot exponent value is specified

-\f2pname\fP
-Specifies a lighting model parameter.
-\%\f3GL_LIGHT_MODEL_AMBIENT\fP,
-\%\f3GL_LIGHT_MODEL_COLOR_CONTROL\fP,
-\%\f3GL_LIGHT_MODEL_LOCAL_VIEWER\fP, and
-\%\f3GL_LIGHT_MODEL_TWO_SIDE\fP are accepted.
-.TP
-\f2params\fP
-Specifies a pointer to the value or values that \f2params\fP will be set to.
-.SH DESCRIPTION
-\%\f3glLightModel\fP sets the lighting model parameter.
-\f2pname\fP names a parameter and \f2params\fP gives the new value.
-There are three lighting model parameters:
-.TP 10
-\%\f3GL_LIGHT_MODEL_AMBIENT\fP
-\f2params\fP contains four integer or floating-point values that specify
-the ambient RGBA intensity of the entire scene.
-Integer values are mapped linearly such that the most positive representable
-value maps to 1.0,
-and the most negative representable value maps to \-1.0.
-Floating-point values are mapped directly.
-Neither integer nor floating-point values are clamped.
-The initial ambient scene intensity is (0.2, 0.2, 0.2, 1.0).
-.TP
-\%\f3GL_LIGHT_MODEL_COLOR_CONTROL\fP
-\f2params\fP must be either \%\f3GL_SEPARATE_SPECULAR_COLOR\fP or
-\%\f3GL_SINGLE_COLOR\fP.
-\%\f3GL_SINGLE_COLOR\fP specifies that a single color is generated from the
-lighting computation for a vertex.  \%\f3GL_SEPARATE_SPECULAR_COLOR\fP
-specifies that the specular color computation of lighting be stored
-separately from the remainder of the lighting computation.  The specular
-color is summed into the generated fragment's color after the application
-of texture mapping (if enabled).  The initial value is \%\f3GL_SINGLE_COLOR\fP.
-.TP
-\%\f3GL_LIGHT_MODEL_LOCAL_VIEWER\fP
-\f2params\fP is a single integer or floating-point value that specifies
-how specular reflection angles are computed.
-If \f2params\fP is 0 (or 0.0), specular reflection angles take the
-view direction to be parallel to and in the direction of the -\f2z\fP axis,
-regardless of the location of the vertex in eye coordinates.
-Otherwise, specular reflections are computed from the origin
-of the eye coordinate system.
-The initial value is 0.
-.TP
-\%\f3GL_LIGHT_MODEL_TWO_SIDE\fP
-\f2params\fP is a single integer or floating-point value that specifies
-whether one- or two-sided lighting calculations are done for polygons.
-It has no effect on the lighting calculations for points,
-lines,
-or bitmaps.
-If \f2params\fP is 0 (or 0.0), one-sided lighting is specified,
-and only the \f2front\fP material parameters are used in the
-lighting equation.
-Otherwise, two-sided lighting is specified.
-In this case, vertices of back-facing polygons are lighted using the
-\f2back\fP material parameters,
-and have their normals reversed before the lighting equation is evaluated.
-Vertices of front-facing polygons are always lighted using the
-\f2front\fP material parameters,
-with no change to their normals. The initial value is 0.
-.P
-In RGBA mode, the lighted color of a vertex is the sum of
-the material emission intensity,
-the product of the material ambient reflectance and the lighting model full-scene 
-ambient intensity,
-and the contribution of each enabled light source.
-Each light source contributes the sum of three terms:
-ambient, diffuse, and specular.
-The ambient light source contribution is the product of the material ambient
-reflectance and the light's ambient intensity.
-The diffuse light source contribution is the product of the material diffuse
-reflectance,
-the light's diffuse intensity,
-and the dot product of the vertex's normal with the normalized vector from
-the vertex to the light source.
-The specular light source contribution is the product of the material specular
-reflectance,
-the light's specular intensity,
-and the dot product of the normalized vertex-to-eye and vertex-to-light
-vectors,
-raised to the power of the shininess of the material.
-All three light source contributions are attenuated equally based on
-the distance from the vertex to the light source and on light source
-direction, spread exponent, and spread cutoff angle.
-All dot products are replaced with 0 if they evaluate to a negative value.
-.P
-The alpha component of the resulting lighted color is set to the alpha value
-of the material diffuse reflectance.
-.P
-In color index mode,
-the value of the lighted index of a vertex ranges from the ambient
-to the specular values passed to \%\f3glMaterial\fP using \%\f3GL_COLOR_INDEXES\fP.
-Diffuse and specular coefficients,
-computed with a (.30, .59, .11) weighting of the lights' colors,
-the shininess of the material,
-and the same reflection and attenuation equations as in the RGBA case,
-determine how much above ambient the resulting index is.

-Specifies a multiplier for each bit in the line stipple pattern.
-If \f2factor\fP is 3,

-\f2factor\fP is clamped to the range [1, 256] and defaults to 1.
-.TP
-\f2pattern\fP
-Specifies a 16-bit integer whose bit pattern determines

-Bit zero is used first; the default pattern is all 1's.
-.SH DESCRIPTION
-Line stippling masks out certain fragments produced by rasterization;
-those fragments will not be drawn.
-The masking is achieved by using three parameters:
-the 16-bit line stipple pattern \f2pattern\fP,
-the repeat count \f2factor\fP,
-and an integer stipple counter $s$. 
-.P
-Counter $s$ is reset to 0 whenever \%\f3glBegin\fP is called,

-counting rectangles rather than groups of fragments.
-.P
-To enable and disable line stippling, call \%\f3glEnable\fP and \%\f3glDisable\fP

-\f2width\fP
-Specifies the width of rasterized lines.
-The initial value is 1.
-.SH DESCRIPTION
-\%\f3glLineWidth\fP specifies the rasterized width of both aliased and antialiased
-lines.
-Using a line width other than 1 has different effects,
-depending on whether line antialiasing is enabled.
-To enable and disable line antialiasing, call 
-\%\f3glEnable\fP and \%\f3glDisable\fP
-with argument \%\f3GL_LINE_SMOOTH\fP. Line antialiasing is initially
-disabled. 
-.P
-If line antialiasing is disabled,
-the actual width is determined by rounding the supplied width
-to the nearest integer.
-(If the rounding results in the value 0,
-it is as if the line width were 1.)
-If
-$| DELTA x | ~>=~ | DELTA y |$,
-\f2i\fP pixels are filled in each column that is rasterized,
-where \f2i\fP is the rounded value of \f2width\fP.
-Otherwise,
-\f2i\fP pixels are filled in each row that is rasterized.
-.P
-If antialiasing is enabled,
-line rasterization produces a fragment for each pixel square
-that intersects the region lying within the rectangle having width
-equal to the current line width,
-length equal to the actual length of the line,
-and centered on the mathematical line segment.
-The coverage value for each fragment is the window coordinate area
-of the intersection of the rectangular region with the corresponding
-pixel square.
-This value is saved and used in the final rasterization step. 
-.P
-Not all widths can be supported when line antialiasing is enabled. If an
-unsupported width is requested, the nearest supported width is used.
-Only width 1 is guaranteed to be supported; others depend on the
-implementation.  Likewise, there is a range for aliased line widths as well.
-To query the range of supported widths and the size
-difference between supported widths within the range, call \%\f3glGet\fP
-with arguments \%\f3GL_ALIASED_LINE_WIDTH_RANGE\fP,
-\%\f3GL_SMOOTH_LINE_WIDTH_RANGE\fP, \%\f3GL_SMOOTH_LINE_WIDTH_GRANULARITY\fP.
-.SH NOTES
-The line width specified by \%\f3glLineWidth\fP is always returned when \%\f3GL_LINE_WIDTH\fP
-is queried.
-Clamping and rounding for aliased and antialiased lines have no effect
-on the specified value.
-.P
-Nonantialiased line width may be clamped to an implementation-dependent
-maximum.  Call \%\f3glGet\fP with \%\f3GL_ALIASED_LINE_WIDTH_RANGE\fP to
-determine the maximum width.

-\f2opcode\fP is a symbolic constant chosen from the list above.
-In the explanation of the logical operations,
-\f2s\fP represents the incoming color index and
-\f2d\fP represents the index in the frame buffer.
-Standard C-language operators are used.
-As these bitwise operators suggest,
-the logical operation is applied independently to each bit pair of the
-source and destination indices or colors.
-.SH NOTES
-Color index logical operations are always supported. RGBA logical
-operations are supported only if the GL version is 1.1 or greater.  
-.P
-When more than one RGBA color or index buffer is enabled for drawing,

-.SH DESCRIPTION
-\%\f3glMaterial\fP assigns values to material parameters.
-There are two matched sets of material parameters.
-One,
-the \f2front-facing\fP set,
-is used to shade points,
-lines,
-bitmaps,
-and all polygons
-(when two-sided lighting is disabled),
-or just front-facing polygons
-(when two-sided lighting is enabled).
-The other set,
-\f2back-facing\fP,
-is used to shade back-facing polygons only when two-sided lighting is enabled.
-Refer to the \%\f3glLightModel\fP reference page for details concerning one- and
-two-sided lighting calculations.
-.P
-\%\f3glMaterial\fP takes three arguments.
-The first,
-\f2face\fP,
-specifies whether the
-\%\f3GL_FRONT\fP materials, the
-\%\f3GL_BACK\fP materials, or both
-\%\f3GL_FRONT_AND_BACK\fP materials will be modified.
-The second,
-\f2pname\fP,
-specifies which of several parameters in one or both sets will be modified.
-The third,
-\f2params\fP,
-specifies what value or values will be assigned to the specified parameter.
-.P
-Material parameters are used in the lighting equation that is optionally
-applied to each vertex.
-The equation is discussed in the \%\f3glLightModel\fP reference page.
-The parameters that can be specified using \%\f3glMaterial\fP,
-and their interpretations by the lighting equation, are as follows:
-.TP 20
-\%\f3GL_AMBIENT\fP
-\f2params\fP contains four integer or floating-point values that specify
-the ambient RGBA reflectance of the material.
-Integer values are mapped linearly such that the most positive representable
-value maps to 1.0,
-and the most negative representable value maps to \-1.0.
-Floating-point values are mapped directly.
-Neither integer nor floating-point values are clamped.
-The initial ambient reflectance for both front- and back-facing materials
-is (0.2, 0.2, 0.2, 1.0).
-.TP
-\%\f3GL_DIFFUSE\fP
-\f2params\fP contains four integer or floating-point values that specify
-the diffuse RGBA reflectance of the material.
-Integer values are mapped linearly such that the most positive representable
-value maps to 1.0,
-and the most negative representable value maps to \-1.0.
-Floating-point values are mapped directly.
-Neither integer nor floating-point values are clamped.
-The initial diffuse reflectance for both front- and back-facing materials
-is (0.8, 0.8, 0.8, 1.0).
-.TP
-\%\f3GL_SPECULAR\fP
-\f2params\fP contains four integer or floating-point values that specify
-the specular RGBA reflectance of the material.
-Integer values are mapped linearly such that the most positive representable
-value maps to 1.0,
-and the most negative representable value maps to \-1.0.
-Floating-point values are mapped directly.
-Neither integer nor floating-point values are clamped.
-The initial specular reflectance for both front- and back-facing materials
-is (0, 0, 0, 1).
-.TP
-\%\f3GL_EMISSION\fP
-\f2params\fP contains four integer or floating-point values that specify
-the RGBA emitted light intensity of the material.
-Integer values are mapped linearly such that the most positive representable
-value maps to 1.0,
-and the most negative representable value maps to \-1.0.
-Floating-point values are mapped directly.
-Neither integer nor floating-point values are clamped.
-The initial emission intensity for both front- and back-facing materials
-is (0, 0, 0, 1).
-.TP
-\%\f3GL_SHININESS\fP
-\f2params\fP is a single integer or floating-point value that specifies
-the RGBA specular exponent of the material.
-Integer and floating-point values are mapped directly.
-Only values in the range [0,128] are accepted.
-The initial specular exponent for both front- and back-facing materials
-is 0.
-.TP
-\%\f3GL_AMBIENT_AND_DIFFUSE\fP
-Equivalent to calling \%\f3glMaterial\fP twice with the same parameter values,
-once with \%\f3GL_AMBIENT\fP and once with \%\f3GL_DIFFUSE\fP.
-.TP
-\%\f3GL_COLOR_INDEXES\fP
-\f2params\fP contains three integer or floating-point values specifying
-the color indices for ambient,
-diffuse,
-and specular lighting.
-These three values,
-and \%\f3GL_SHININESS\fP,
-are the only material values used by the color index mode lighting equation.
-Refer to the \%\f3glLightModel\fP reference page for a discussion 
-of color index lighting.
-.SH NOTES
-The material parameters can be updated at any time.
-In particular,
-\%\f3glMaterial\fP can be called between a call to \%\f3glBegin\fP and the corresponding
-call to \%\f3glEnd\fP.
-If only a single material parameter is to be changed per vertex,
-however,
-\%\f3glColorMaterial\fP is preferred over \%\f3glMaterial\fP
-(see \%\f3glColorMaterial\fP).
-.P
-While the ambient, diffuse, specular and emission material parameters
-all have alpha components, only the diffuse alpha component is used in
-the lighting computation.
-.SH ERRORS
-\%\f3GL_INVALID_ENUM\fP is generated if either \f2face\fP or \f2pname\fP is not
-an accepted value.
-.P
-\%\f3GL_INVALID_VALUE\fP is generated if a specular exponent outside the range
-[0,128] is specified.

-.SH DESCRIPTION
-\%\f3glMultiTexCoordARB\fP specifies texture coordinates in one, two, three, or four

-\%\f3glMultiTexCoord4ARB\fP
-defines all four components explicitly as

-.P
-The current texture coordinates are part of the data

-.SH NOTES
-\%\f3glMultiTexCoordARB\fP is only supported if \%\f3GL_ARB_multitexture\fP is included in the

-\%\f3glNewList\fP has two arguments.

-Names can be created and reserved with \%\f3glGenLists\fP
-and tested for uniqueness with \%\f3glIsList\fP.

-is a symbolic constant that can assume one of two values: 
-.TP 30
-\%\f3GL_COMPILE\fP
-Commands are merely compiled.
-.TP 
-\%\f3GL_COMPILE_AND_EXECUTE\fP
-Commands are executed as they are compiled into the display list.
-.P
-Certain commands are not compiled into the display list
-but are executed immediately,
-regardless of the display-list mode.
-These commands are
-\%\f3glAreTexturesResident\fP,
-\%\f3glColorPointer\fP,
-\%\f3glDeleteLists\fP,
-\%\f3glDeleteTextures\fP,

-.P
-Similarly, 
-\%\f3glTexImage1D\fP, \%\f3glTexImage2D\fP, and \%\f3glTexImage3D\fP
-are executed immediately and not compiled into the display list when their
-first argument is \%\f3GL_PROXY_TEXTURE_1D\fP, \%\f3GL_PROXY_TEXTURE_1D\fP, or
-\%\f3GL_PROXY_TEXTURE_3D\fP, respectively.
-.P
-When the \%\f3GL_ARB_imaging\fP extension is supported,
-\%\f3glHistogram\fP executes immediately when its argument is
-\%\f3GL_PROXY_HISTOGRAM\fP.  Similarly, \%\f3glColorTable\fP executes
-immediately when its first argument is \%\f3glPROXY_COLOR_TABLE\fP,
-\%\f3glPROXY_POST_CONVOLUTION_COLOR_TABLE\fP, or
-\%\f3glPROXY_POST_COLOR_MATRIX_COLOR_TABLE\fP.
-.P
-When the \%\f3GL_ARB_multitexture\fP extension is supported,
-\%\f3glClientActiveTextureARB\fP is not compiled into display lists, but
-executed immediately.
-.P
-When \%\f3glEndList\fP is encountered,
-the display-list definition is completed by associating the list
-with the unique name \f2list\fP
-(specified in the \%\f3glNewList\fP command). 
-If a display list with name \f2list\fP already exists,
-it is replaced only when \%\f3glEndList\fP is called.

-\%\f3glCallList\fP and \%\f3glCallLists\fP can be entered into display lists.
-Commands in the display list or lists executed by \%\f3glCallList\fP
-or \%\f3glCallLists\fP are not included in the display list being created,
-even if the list creation mode is \%\f3GL_COMPILE_AND_EXECUTE\fP.
-.P
-A display list is just a group of commands and arguments, so errors
-generated by commands in a display list must be generated when the list is
-executed. If the list is created in \%\f3GL_COMPILE\fP mode, errors are
-not generated until the list is executed.
-.SH ERRORS
-\%\f3GL_INVALID_VALUE\fP is generated if \f2list\fP is 0.

-or if \%\f3glNewList\fP is called while a display list is being defined.
-.P
-\%\f3GL_INVALID_OPERATION\fP is generated if \%\f3glNewList\fP or \%\f3glEndList\fP
-is executed between the execution of \%\f3glBegin\fP
-and the corresponding execution of \%\f3glEnd\fP.
-.P
-\%\f3GL_OUT_OF_MEMORY\fP is generated if there is insufficient memory to

-The current normal is set to the given coordinates

-Normals specified with \%\f3glNormal\fP need not have unit length.
-If \%\f3GL_NORMALIZE\fP is enabled,

-If \%\f3GL_RESCALE_NORMAL\fP is enabled, normals are scaled by a scaling factor
-derived from the modelview matrix.  \%\f3GL_RESCALE_NORMAL\fP requires that the

-.SH DESCRIPTION
-\%\f3glNormalPointer\fP specifies the location and data  of an array of normals
-to use when rendering.
-\f2type\fP specifies the data type of
-the normal coordinates and \f2stride\fP gives the byte stride from one
-normal to the next, allowing vertices and attributes

-.SH DESCRIPTION
-
-\%\f3glPixelStore\fP sets pixel storage modes that affect the operation of subsequent
-\%\f3glDrawPixels\fP and \%\f3glReadPixels\fP as well as the unpacking of
-polygon stipple patterns (see \%\f3glPolygonStipple\fP), bitmaps (see
-\%\f3glBitmap\fP), texture patterns (see \%\f3glTexImage1D\fP,
-\%\f3glTexImage2D\fP, \%\f3glTexImage3D\fP, \%\f3glTexSubImage1D\fP,
-\%\f3glTexSubImage2D\fP, \%\f3glTexSubImage3D\fP).
-Additionally, if the \%\f3GL_ARB_imaging\fP extension is supported, pixle
-storage modes affect convlution filters
-(see \%\f3glConvolutionFilter1D\fP, \%\f3glConvolutionFilter2D\fP, and
-\%\f3glSeparableFilter2D\fP, color table (see \%\f3glColorTable\fP, and 
-\%\f3glColorSubTable\fP, and unpacking histogram (See \%\f3glHistogram\fP),
-and minmax (See \%\f3glMinmax\fP) data.
-.P
-\f2pname\fP is a symbolic constant indicating the parameter to be set, and
-\f2param\fP is the new value.  Six of the twelve storage parameters affect
-how pixel data is returned to client memory.
-They are as follows:
-.TP 10
-\%\f3GL_PACK_SWAP_BYTES\fP
-If true,
-byte ordering for multibyte color components,
-depth components,
-color indices,
-or stencil indices
-is reversed.
-That is,
-if a four-byte component consists of bytes
-$b sub 0$,
-$b sub 1$,
-$b sub 2$,
-$b sub 3$,
-it is stored in memory as
-$b sub 3$,
-$b sub 2$,
-$b sub 1$,
-$b sub 0$
-if \%\f3GL_PACK_SWAP_BYTES\fP is true.
-\%\f3GL_PACK_SWAP_BYTES\fP has no effect on the memory order of components
-within a pixel,
-only on the order of bytes within components or indices.
-For example,
-the three components of a \%\f3GL_RGB\fP  pixel are always stored with
-red first,
-green second,
-and blue third,
-regardless of the value of \%\f3GL_PACK_SWAP_BYTES\fP.
-.TP
-\%\f3GL_PACK_LSB_FIRST\fP
-If true,
-bits are ordered within a byte from least significant to most significant;
-otherwise,
-the first bit in each byte is the most significant one.
-This parameter is significant for bitmap data only.
-.TP
-\%\f3GL_PACK_ROW_LENGTH\fP
-If greater than 0,
-\%\f3GL_PACK_ROW_LENGTH\fP defines the number of pixels in a row.
-If the first pixel of a row is placed at location $p$ in memory,
-then the location of the first pixel of the next row is obtained by skipping
-.sp
-.ce
-$k ~=~~ left  { ^ lpile { n l above {a over s left ceiling { s n l } over a right ceiling}} ~~ lpile {s ~>=~ a above s ~<~ a }$
-.sp
-components or indices,
-where $n$ is the number of components or indices in a pixel,
-$l$ is the number of pixels in a row
-(\%\f3GL_PACK_ROW_LENGTH\fP if it is greater than 0,
-the $width$ argument to the pixel routine otherwise),
-$a$ is the value of \%\f3GL_PACK_ALIGNMENT\fP, and
-$s$ is the size, in bytes, of a single component
-(if $ a < s$, then it is as if $a ~=~ s$).
-In the case of 1-bit values,
-the location of the next row is obtained by skipping
-.sp
-.ce
-$k ~=~ 8 a left ceiling { n l } over { 8 a } ^ right ceiling$
-.sp
-components or indices.
-.IP
-The word \f2component\fP in this description refers to the nonindex values
-red,
-green,
-blue,
-alpha,
-and depth.
-Storage  \%\f3GL_RGB\fP,
-for example,
-has three components per pixel:
-first red,
-then green,
-and finally blue.
-.TP
-\%\f3GL_PACK_IMAGE_HEIGHT\fP
-If greater than 0,
-\%\f3GL_PACK_IMAGE_HEIGHT\fP defines the number of pixels in an image
-three-dimensional texture volume.
-Where ``image'' is defined by all pixels sharing the same third
-dimension index.
-If the first pixel of a row is placed at location $p$ in memory,
-then the location of the first pixel of the next row is obtained by skipping
-.sp
-.ce
-$k ~=~~ left  { ~ lpile { n l h above {a over s left ceiling { s n l h }
-over a ^ right ceiling}} ~~ lpile {s ~>=~  a above s ~<~  a }$
-.sp
-components or indices, where $n$ is the number of components or indices
-in a pixel, $l$ is the number of pixels in a row
-(\%\f3GL_PACK_ROW_LENGTH\fP if it is greater than 0,  the
-$width$ argument to \%\f3glTexImage3d\fP otherwise), $h$ is the number of
-rows in a pixel image (\%\f3GL_PACK_IMAGE_HEIGHT\fP if it is greater than
-0, the $height$ argument to the \%\f3glTexImage3D\fP routine otherwise),
-$a$ is the value of
-\%\f3GL_PACK_ALIGNMENT\fP, and $s$ is the size, in bytes, of a single
-component (if $ a < s$, then it is as if $a = s$).
-.IP
-The word \f2component\fP in this description refers to the nonindex values
-red,
-green,
-blue,
-alpha,
-and depth.
-Storage  \%\f3GL_RGB\fP,
-for example,
-has three components per pixel:
-first red,
-then green,
-and finally blue.
-.TP
-\%\f3GL_PACK_SKIP_PIXELS\fP, \%\f3GL_PACK_SKIP_ROWS\fP, and \%\f3GL_PACK_SKIP_IMAGES\fP
-These values are provided as a convenience to the programmer;
-they provide no functionality that cannot be duplicated simply by
-incrementing the pointer passed to \%\f3glReadPixels\fP.
-Setting \%\f3GL_PACK_SKIP_PIXELS\fP to $i$ is equivalent to incrementing
-the pointer by $i n$ components or indices,
-where $n$ is the number of components or indices in each pixel.
-Setting \%\f3GL_PACK_SKIP_ROWS\fP to $j$ is equivalent to incrementing
-the pointer by $j m$ components or indices,
-where $m$ is the number of components or indices per row,
-as just computed in the \%\f3GL_PACK_ROW_LENGTH\fP section.
-Setting \%\f3GL_PACK_SKIP_IMAGES\fP to $k$ is equivalent to incrementing
-the pointer by $k p$, where $p$ is the number of components or indices
-per image, as computed in the \%\f3GL_PACK_IMAGE_HEIGHT\fP section.
-.TP
-\%\f3GL_PACK_ALIGNMENT\fP
-Specifies the alignment requirements for the start of each pixel row in memory.
-The allowable values are 
-1 (byte-alignment),
-2 (rows aligned to even-numbered bytes),
-4 (word-alignment), and
-8 (rows start on double-word boundaries).
-.P
-The other six of the twelve storage parameters affect how pixel data is
-read from client memory.
-These values are significant for \%\f3glDrawPixels\fP,
-\%\f3glTexImage1D\fP,
-\%\f3glTexImage2D\fP,
-\%\f3glTexImage3D\fP,
-\%\f3glTexSubImage1D\fP,
-\%\f3glTexSubImage2D\fP,
-\%\f3glTexSubImage3D\fP,
-\%\f3glBitmap\fP, and
-\%\f3glPolygonStipple\fP.
-.P
-Additionally, if the \%\f3GL_ARB_imaging\fP extension is supported,
-\%\f3glColorTable\fP,
-\%\f3glColorSubTable\fP,
-\%\f3glConvolutionFilter1D\fP,
-\%\f3glConvolutionFilter2D\fP, and
-\%\f3glSeparableFilter2D\fP.
-They are as follows:
-.TP
-\%\f3GL_UNPACK_SWAP_BYTES\fP
-If true,
-byte ordering for multibyte color components,
-depth components,
-color indices,
-or stencil indices
-is reversed.
-That is,
-if a four-byte component consists of bytes
-$b sub 0$,
-$b sub 1$,
-$b sub 2$,
-$b sub 3$,
-it is taken from memory as
-$b sub 3$,
-$b sub 2$,
-$b sub 1$,

-\%\f3glPixelTransfer\fP sets pixel transfer modes that affect the operation of subsequent
-\%\f3glCopyPixels\fP,
-\%\f3glCopyTexImage1D\fP,
-\%\f3glCopyTexImage2D\fP,
-\%\f3glCopyTexSubImage1D\fP,
-\%\f3glCopyTexSubImage2D\fP,
-\%\f3glCopyTexSubImage3D\fP,
-\%\f3glDrawPixels\fP,
-\%\f3glReadPixels\fP,
-\%\f3glTexImage1D\fP,
-\%\f3glTexImage2D\fP,
-\%\f3glTexImage3D\fP,
-\%\f3glTexSubImage1D\fP,
-\%\f3glTexSubImage2D\fP, and
-\%\f3glTexSubImage3D\fP commands.
-Additionally, if the \%\f3GL_ARB_imaging\fP subset is supported, the
-routines
-\%\f3glColorTable\fP,
-\%\f3glColorSubTable\fP,
-\%\f3glConvolutionFilter1D\fP,
-\%\f3glConvolutionFilter2D\fP,
-\%\f3glHistogram\fP,
-\%\f3glMinmax\fP, and
-\%\f3glSeparableFilter2D\fP are also affected.
-The algorithms that are specified by pixel transfer modes operate on
-pixels after they are read from the frame buffer
-(\%\f3glCopyPixels\fP
-\%\f3glCopyTexImage1D\fP,
-\%\f3glCopyTexImage2D\fP,
-\%\f3glCopyTexSubImage1D\fP,
-\%\f3glCopyTexSubImage2D\fP,
-\%\f3glCopyTexSubImage3D\fP, and
-\%\f3glReadPixels\fP),
-or unpacked from client memory
-(\%\f3glDrawPixels\fP, \%\f3glTexImage1D\fP, \%\f3glTexImage2D\fP, \%\f3glTexImage3D\fP,
-\%\f3glTexSubImage1D\fP, \%\f3glTexSubImage2D\fP, and \%\f3glTexSubImage3D\fP). 
-Pixel transfer operations happen in the same order,
-and in the same manner,
-regardless of the command that resulted in the pixel operation.
-Pixel storage modes
-(see \%\f3glPixelStore\fP)
-control the unpacking of pixels being read from client memory,
-and the packing of pixels being written back into client memory.
-.P
-Pixel transfer operations handle four fundamental pixel types:
-\f2color\fP,
-\f2color index\fP,
-\f2depth\fP, and
-\f2stencil\fP.
-\f2Color\fP pixels consist of four floating-point values
-with unspecified mantissa and exponent sizes,
-scaled such that 0 represents zero intensity
-and 1 represents full intensity.
-\f2Color indices\fP comprise a single fixed-point value,
-with unspecified precision to the right of the binary point.
-\f2Depth\fP pixels comprise a single floating-point value,
-with unspecified mantissa and exponent sizes,
-scaled such that 0.0 represents the minimum depth buffer value,
-and 1.0 represents the maximum depth buffer value.
-Finally,
-\f2stencil\fP pixels comprise a single fixed-point value,
-with unspecified precision to the right of the binary point.
-.BP
-.P
-The pixel transfer operations performed on the four basic pixel types are 
-as follows:
-.TP 12
-Color
-Each of the four color components is multiplied by a scale factor,
-then added to a bias factor.
-That is,
-the red component is multiplied by \%\f3GL_RED_SCALE\fP,
-then added to \%\f3GL_RED_BIAS\fP;
-the green component is multiplied by \%\f3GL_GREEN_SCALE\fP,
-then added to \%\f3GL_GREEN_BIAS\fP;
-the blue component is multiplied by \%\f3GL_BLUE_SCALE\fP,
-then added to \%\f3GL_BLUE_BIAS\fP; and
-the alpha component is multiplied by \%\f3GL_ALPHA_SCALE\fP,
-then added to \%\f3GL_ALPHA_BIAS\fP.
-After all four color components are scaled and biased,
-each is clamped to the range [0,1].
-All color, scale, and bias values are specified with \%\f3glPixelTransfer\fP.
-.IP
-If \%\f3GL_MAP_COLOR\fP is true,
-each color component is scaled by the size of the corresponding
-color-to-color map,
-then replaced by the contents of that map indexed by the scaled component.
-That is,
-the red component is scaled by \%\f3GL_PIXEL_MAP_R_TO_R_SIZE\fP,
-then replaced by the contents of \%\f3GL_PIXEL_MAP_R_TO_R\fP indexed by itself.
-The green component is scaled by \%\f3GL_PIXEL_MAP_G_TO_G_SIZE\fP,
-then replaced by the contents of \%\f3GL_PIXEL_MAP_G_TO_G\fP indexed by itself.
-The blue component is scaled by \%\f3GL_PIXEL_MAP_B_TO_B_SIZE\fP,
-then replaced by the contents of \%\f3GL_PIXEL_MAP_B_TO_B\fP indexed by itself.
-And
-the alpha component is scaled by \%\f3GL_PIXEL_MAP_A_TO_A_SIZE\fP,
-then replaced by the contents of \%\f3GL_PIXEL_MAP_A_TO_A\fP indexed by itself.
-All components taken from the maps are then clamped to the range [0,1].
-\%\f3GL_MAP_COLOR\fP is specified with \%\f3glPixelTransfer\fP.
-The contents of the various maps are specified with \%\f3glPixelMap\fP.
-.IP
-If the \%\f3GL_ARB_imaging\fP extension is supported, each of the four
-color components may be scaled and biased after transformation by the
-color matrix.  
-That is,
-the red component is multiplied by \%\f3GL_POST_COLOR_MATRIX_RED_SCALE\fP,
-then added to \%\f3GL_POST_COLOR_MATRIX_RED_BIAS\fP;
-the green component is multiplied by \%\f3GL_POST_COLOR_MATRIX_GREEN_SCALE\fP,
-then added to \%\f3GL_POST_COLOR_MATRIX_GREEN_BIAS\fP;
-the blue component is multiplied by \%\f3GL_POST_COLOR_MATRIX_BLUE_SCALE\fP,
-then added to \%\f3GL_POST_COLOR_MATRIX_BLUE_BIAS\fP; and
-the alpha component is multiplied by \%\f3GL_POST_COLOR_MATRIX_ALPHA_SCALE\fP,
-then added to \%\f3GL_POST_COLOR_MATRIX_ALPHA_BIAS\fP.
-After all four color components are scaled and biased,
-each is clamped to the range [0,1].
-.IP
-Similiarly, if the \%\f3GL_ARB_imaging\fP extension is supported, each of
-the four color components may be scaled and biased after processing by
-the enabled convolution filter.
-That is,
-the red component is multiplied by \%\f3GL_POST_CONVOLUTION_RED_SCALE\fP,
-then added to \%\f3GL_POST_CONVOLUTION_RED_BIAS\fP;
-the green component is multiplied by \%\f3GL_POST_CONVOLUTION_GREEN_SCALE\fP,
-then added to \%\f3GL_POST_CONVOLUTION_GREEN_BIAS\fP;
-the blue component is multiplied by \%\f3GL_POST_CONVOLUTION_BLUE_SCALE\fP,
-then added to \%\f3GL_POST_CONVOLUTION_BLUE_BIAS\fP; and
-the alpha component is multiplied by \%\f3GL_POST_CONVOLUTION_ALPHA_SCALE\fP,
-then added to \%\f3GL_POST_CONVOLUTION_ALPHA_BIAS\fP.
-After all four color components are scaled and biased,
-each is clamped to the range [0,1].
-.TP
-Color index
-Each color index is shifted left by \%\f3GL_INDEX_SHIFT\fP bits; any bits
-beyond the number of fraction bits carried
-by the fixed-point index are filled with zeros.
-If \%\f3GL_INDEX_SHIFT\fP is negative,
-the shift is to the right,
-again zero filled.
-Then \%\f3GL_INDEX_OFFSET\fP is added to the index.
-\%\f3GL_INDEX_SHIFT\fP and \%\f3GL_INDEX_OFFSET\fP are specified with 
-.br
-\%\f3glPixelTransfer\fP.
-.IP
-From this point, operation diverges depending on the required  of
-the resulting pixels.
-If the resulting pixels are to be written to a color index buffer,
-or if they are being read back to client memory in \%\f3GL_COLOR_INDEX\fP ,
-the pixels continue to be treated as indices.
-If \%\f3GL_MAP_COLOR\fP is true,
-each index is masked by $2 sup n ~-~ 1$,
-where $n$ is \%\f3GL_PIXEL_MAP_I_TO_I_SIZE\fP,
-then replaced by the contents of \%\f3GL_PIXEL_MAP_I_TO_I\fP indexed by the
-masked value.
-\%\f3GL_MAP_COLOR\fP is specified with \%\f3glPixelTransfer\fP.
-The contents of the index map is specified with \%\f3glPixelMap\fP.
-.IP
-If the resulting pixels are to be written to an RGBA color buffer,
-or if they are read back to client memory in a  other than
-\%\f3GL_COLOR_INDEX\fP,
-the pixels are converted from indices to colors by referencing the
-four maps
-\%\f3GL_PIXEL_MAP_I_TO_R\fP,
-\%\f3GL_PIXEL_MAP_I_TO_G\fP,
-\%\f3GL_PIXEL_MAP_I_TO_B\fP, and
-\%\f3GL_PIXEL_MAP_I_TO_A\fP.
-Before being dereferenced,
-the index is masked by $2 sup n ~-~ 1$,
-where $n$ is
-\%\f3GL_PIXEL_MAP_I_TO_R_SIZE\fP for the red map,
-\%\f3GL_PIXEL_MAP_I_TO_G_SIZE\fP for the green map,
-\%\f3GL_PIXEL_MAP_I_TO_B_SIZE\fP for the blue map, and
-\%\f3GL_PIXEL_MAP_I_TO_A_SIZE\fP for the alpha map.
-All components taken from the maps are then clamped to the range [0,1].
-The contents of the four maps is specified with \%\f3glPixelMap\fP.
-.TP
-Depth
-Each depth value is multiplied by \%\f3GL_DEPTH_SCALE\fP,
-added to \%\f3GL_DEPTH_BIAS\fP,
-then clamped to the range [0,1].
-.TP
-Stencil
-Each index is shifted \%\f3GL_INDEX_SHIFT\fP bits just as a color index is,
-then added to \%\f3GL_INDEX_OFFSET\fP.
-If \%\f3GL_MAP_STENCIL\fP is true,
-each index is masked by $2 sup n ~-~ 1$,
-where $n$ is \%\f3GL_PIXEL_MAP_S_TO_S_SIZE\fP,
-then replaced by the contents of \%\f3GL_PIXEL_MAP_S_TO_S\fP indexed by the
-masked value.

-\f2size\fP
-Specifies the diameter of rasterized points.

-.SH DESCRIPTION
-\%\f3glPointSize\fP specifies the rasterized diameter of both aliased and antialiased
-points.
-Using a point size other than 1 has different effects,
-depending on whether point antialiasing is enabled.
-To enable and disable point antialiasing, call 
-\%\f3glEnable\fP and \%\f3glDisable\fP
-with argument \%\f3GL_POINT_SMOOTH\fP. Point antialiasing is initially disabled.
-.P
-If point antialiasing is disabled,
-the actual size is determined by rounding the supplied size
-to the nearest integer.
-(If the rounding results in the value 0,
-it is as if the point size were 1.)
-If the rounded size is odd,
-then the center point
-($ x $, $ y $)
-of the pixel fragment that represents the point is computed as
-.sp
-.ce
-( $ \(lf ~ x sub w ~ \(rf ~+~ .5 $, $ \(lf ~ y sub w ~ \(rf ~+~ .5 $)
-.sp
-where $w$ subscripts indicate window coordinates.
-All pixels that lie within the square grid of the rounded size centered at
-($ x $, $ y $)
-make up the fragment.
-If the size is even,
-the center point is
-.sp
-.ce
-( $ \(lf ~ x sub w ~+~ .5 ~ \(rf$, $ \(lf ~ y sub w ~+~ .5 ~ \(rf $)
-.sp
-and the rasterized fragment's centers are the half-integer window coordinates
-within the square of the rounded size centered at
-($ x $, $ y $).
-All pixel fragments produced in rasterizing a nonantialiased point are
-assigned the same associated data,
-that of the vertex corresponding to the point.
-.P
-If antialiasing is enabled,
-then point rasterization produces a fragment for each pixel square
-that intersects the region lying within the circle having diameter
-equal to the current point size and centered at the point's
-($ x sub w $, $ y sub w $).
-The coverage value for each fragment is the window coordinate area
-of the intersection of the circular region with the corresponding pixel square.
-This value is saved and used in the final rasterization step. 
-The data associated with each fragment is the data associated with 
-the point being rasterized.
-.P
-Not all sizes are supported when point antialiasing is enabled. 
-If an unsupported size is requested,
-the nearest supported size is used.
-Only size 1 is guaranteed to be supported;
-others depend on the implementation.
-To query the range of supported sizes and the size difference between
-supported sizes within the range, call
-\%\f3glGet\fP with arguments
-\%\f3GL_SMOOTH_POINT_SIZE_RANGE\fP and
-\%\f3GL_SMOOTH_POINT_SIZE_GRANULARITY\fP.
-For aliased points, query the supported ranges and granularity with
-\%\f3glGet\fP with arguments
-\%\f3GL_ALIASED_POINT_SIZE_RANGE\fP and
-\%\f3GL_ALIASED_POINT_SIZE_GRANULARITY\fP.
-.SH NOTES
-The point size specified by \%\f3glPointSize\fP is always returned when \%\f3GL_POINT_SIZE\fP
-is queried.
-Clamping and rounding for aliased and antialiased points have no effect
-on the specified value.
-.P
-A non-antialiased point size may be clamped to an implementation-dependent
-maximum.
-Although this maximum cannot be queried,
-it must be no less than the maximum value for antialiased points,
-rounded to the nearest integer value.

-.fi
-
-.SH PARAMETERS
-.TP \w'\f2face\fP\ \ 'u 
-\f2face\fP
-Specifies the polygons that \f2mode\fP applies to.
-Must be
-\%\f3GL_FRONT\fP for front-facing polygons,
-\%\f3GL_BACK\fP for back-facing polygons,
-or \%\f3GL_FRONT_AND_BACK\fP for front- and back-facing polygons.
-.TP
-\f2mode\fP
-Specifies how polygons will be rasterized.
-Accepted values are
-\%\f3GL_POINT\fP,
-\%\f3GL_LINE\fP, and
-\%\f3GL_FILL\fP.
-The initial value is \%\f3GL_FILL\fP for both front- and back-facing polygons.
-.SH DESCRIPTION
-\%\f3glPolygonMode\fP controls the interpretation of polygons for rasterization.
-\f2face\fP describes which polygons \f2mode\fP applies to:
-front-facing polygons (\%\f3GL_FRONT\fP),
-back-facing polygons (\%\f3GL_BACK\fP),
-or both (\%\f3GL_FRONT_AND_BACK\fP).
-The polygon mode affects only the final rasterization of polygons.
-In particular,
-a polygon's vertices are lit and
-the polygon is clipped and possibly culled before these modes are applied.
-.P
-Three modes are defined and can be specified in \f2mode\fP:
-.TP 14
-\%\f3GL_POINT\fP
-Polygon vertices that are marked as the start of a boundary edge
-are drawn as points.
-Point attributes such as
-\%\f3GL_POINT_SIZE\fP and
-\%\f3GL_POINT_SMOOTH\fP control
-the rasterization of the points.
-Polygon rasterization attributes other than \%\f3GL_POLYGON_MODE\fP have no effect.
-.TP
-\%\f3GL_LINE\fP
-Boundary edges of the polygon are drawn as line segments.
-They are treated as connected line segments for line stippling;
-the line stipple counter and pattern are not reset between segments
-(see \%\f3glLineStipple\fP).
-Line attributes such as
-\%\f3GL_LINE_WIDTH\fP and
-\%\f3GL_LINE_SMOOTH\fP control
-the rasterization of the lines.
-Polygon rasterization attributes other than \%\f3GL_POLYGON_MODE\fP have no effect.
-.TP
-\%\f3GL_FILL\fP
-The interior of the polygon is filled.
-Polygon attributes such as
-\%\f3GL_POLYGON_STIPPLE\fP and
-\%\f3GL_POLYGON_SMOOTH\fP control the rasterization of the polygon.
-.SH EXAMPLES
-To draw a surface with filled back-facing polygons
-and outlined front-facing polygons,
-call
-.Ex 1
-glPolygonMode(\%\f3GL_FRONT\fP, \%\f3GL_LINE\fP);
-.Ee
-.SH NOTES
-Vertices are marked as boundary or nonboundary with an edge flag.
-Edge flags are generated internally by the GL when it decomposes
-polygons; they can be set explicitly using \%\f3glEdgeFlag\fP.
-.SH ERRORS
-\%\f3GL_INVALID_ENUM\fP is generated if either \f2face\fP or \f2mode\fP is not
-an accepted value.
-.P
-\%\f3GL_INVALID_OPERATION\fP is generated if \%\f3glPolygonMode\fP

-\f2mask\fP
-Specifies a pointer to a $32 ~times~ 32$ stipple pattern that will be unpacked

-.SH DESCRIPTION
-Polygon stippling,
-like line stippling
-(see \%\f3glLineStipple\fP),
-masks out certain fragments produced by rasterization,
-creating a pattern.
-Stippling is independent of polygon antialiasing.
-.P
-\f2mask\fP is a pointer to a $32 ~times~ 32$ stipple pattern that is stored

-and
-.I width
-both equal to 32, a pixel 
-of \%\f3GL_COLOR_INDEX\fP, and data type 
-of \%\f3GL_BITMAP\fP.
-That is,
-the stipple pattern is represented as a $32 ~times~ 32$ array
-of 1-bit color indices packed in unsigned bytes.
-\%\f3glPixelStore\fP parameters like \%\f3GL_UNPACK_SWAP_BYTES\fP
-and \%\f3GL_UNPACK_LSB_FIRST\fP affect the assembling of the bits into a
-stipple pattern.
-Pixel transfer operations
-(shift, offset, pixel map)
-are not applied to the stipple image,
-however.
-.P
-To enable and disable polygon stippling, call
-\%\f3glEnable\fP and \%\f3glDisable\fP
-with argument \%\f3GL_POLYGON_STIPPLE\fP. Polygon stippling is initially
-disabled. If it's enabled,
-a rasterized polygon fragment with window coordinates $x sub w$ and $y sub w$
-is sent to the next stage of the GL if and only if the
-($x sub w~roman mod~32$)th bit in the ($y sub w~roman mod~32$)th row
-of the stipple pattern is 1 (one).
-When polygon stippling is disabled, it is as if the stipple pattern
-consists of all 1's.

-Specifies an array containing the texture priorities.
-A priority given in an element of \f2priorities\fP applies to the texture

-.SH DESCRIPTION
-\%\f3glPrioritizeTextures\fP assigns the \f2n\fP texture priorities given in \f2priorities\fP to the
-\f2n\fP textures named in \f2textures\fP.
-.P
-The GL establishes
-a ``working set'' of textures that are resident in texture memory.
-These textures may be bound to a texture target much more efficiently
-than textures that are not resident.
-By specifying a priority for each texture,
-\%\f3glPrioritizeTextures\fP allows applications to guide the GL implementation in determining
-which textures should be resident.
-.P
-The priorities given in \f2priorities\fP are clamped to the range [0,\1]
-before they are assigned.
-0 indicates the lowest priority; textures with priority 0
-are least likely to be resident.
-1 indicates the highest priority; textures with priority 1
-are most likely to be resident.
-However, textures are not guaranteed to be resident until they are used.
-.P
-\%\f3glPrioritizeTextures\fP silently ignores attempts to prioritize texture 0, or any texture
-name that does not correspond to an existing texture.
-.P
-\%\f3glPrioritizeTextures\fP does not require that any of the textures named by \f2textures\fP
-be bound to a texture target.
-\%\f3glTexParameter\fP may also be used to set a texture's priority,
-but only if the texture is currently bound.
-This is the only way to set the priority of a default texture.

-
-.SH DESCRIPTION
-\%\f3glPushClientAttrib\fP takes one argument,
-a mask that indicates which groups of client-state variables
-to save on the client attribute stack.
-Symbolic constants are used to set bits in the mask.
-\f21.1\fP

-(the second column lists which attributes are saved):

-\%\f3GL_CLIENT_VERTEX_ARRAY_BIT\fP	Vertex arrays (and enables)
-.P
-\%\f3glPopClientAttrib\fP restores the values of the client-state variables
-saved with the last \%\f3glPushClientAttrib\fP.
-Those not saved are left unchanged.
-.P
-It is an error to push attributes onto a full client attribute stack,
-or to pop attributes off an empty stack.
-In either case, the error flag is set,
-and no other change is made to GL state.
-.P
-Initially, the client attribute stack is empty.
-.SH NOTES
-\%\f3glPushClientAttrib\fP is available only if the GL version is 1.1 or greater.
-.P
-Not all values for GL client state can be saved on the attribute stack.
-For example, select and feedback state cannot be saved.
-.P
-The depth of the attribute stack depends on the implementation,
-but it must be at least 16.
-.P
-Use \%\f3glPushAttrib\fP and \%\f3glPopAttrib\fP to push and restore
-state which is kept on the server. Only pixel storage modes and

-\f2v\fP
-Specifies a pointer to an array of two,
-three,
-or four elements,
-specifying $x$, $y$, $z$, and $w$ coordinates, respectively.
-.SH DESCRIPTION
-The GL maintains a 3D position in window coordinates.
-This position,
-called the raster position,
-is used to position pixel and bitmap write operations. It is
-maintained with subpixel accuracy.
-See \%\f3glBitmap\fP, \%\f3glDrawPixels\fP, and \%\f3glCopyPixels\fP.
-.P
-The current raster position consists of three window coordinates
-($x$, $y$, $z$),
-a clip coordinate value ($w$),
-an eye coordinate distance,
-a valid bit,
-and associated color data and texture coordinates.
-The $w$ coordinate is a clip coordinate,
-because $w$ is not projected to window coordinates.
-\%\f3glRasterPos4\fP specifies object coordinates $x$, $y$, $z$, and $w$
-explicitly.
-\%\f3glRasterPos3\fP specifies object coordinate $x$, $y$, and $z$ explicitly,
-while $w$ is implicitly set to 1.
-\%\f3glRasterPos2\fP uses the argument values for $x$ and $y$ while
-implicitly setting $z$ and $w$ to 0 and 1.  
-.P
-The object coordinates presented by \%\f3glRasterPos\fP are treated just like those
-of a \%\f3glVertex\fP command:
-They are transformed by the current modelview and projection matrices
-and passed to the clipping stage.
-If the vertex is not culled,
-then it is projected and scaled to window coordinates,
-which become the new current raster position,
-and the \%\f3GL_CURRENT_RASTER_POSITION_VALID\fP flag is set.
-If the vertex 
-.I is
-culled,
-then the valid bit is cleared and the current raster position
-and associated color and texture coordinates are undefined.
-.P
-The current raster position also includes some associated color data
-and texture coordinates.
-If lighting is enabled,
-then \%\f3GL_CURRENT_RASTER_COLOR\fP
-(in RGBA mode)
-or \%\f3GL_CURRENT_RASTER_INDEX\fP
-(in color index mode)
-is set to the color produced by the lighting calculation
-(see \%\f3glLight\fP, \%\f3glLightModel\fP, and 
-.br
-\%\f3glShadeModel\fP).
-If lighting is disabled, 
-current color
-(in RGBA mode, state variable \%\f3GL_CURRENT_COLOR\fP)
-or color index
-(in color index mode, state variable \%\f3GL_CURRENT_INDEX\fP)
-is used to update the current raster color.
-.P
-Likewise,
-\%\f3GL_CURRENT_RASTER_TEXTURE_COORDS\fP is updated as a function
-of \%\f3GL_CURRENT_TEXTURE_COORDS\fP,
-based on the texture matrix and the texture generation functions
-(see \%\f3glTexGen\fP).
-Finally,
-the distance from the origin of the eye coordinate system to the
-vertex as transformed by only the modelview matrix replaces
-\%\f3GL_CURRENT_RASTER_DISTANCE\fP.
-.P
-Initially, the current raster position is (0, 0, 0, 1),
-the current raster distance is 0,
-the valid bit is set,
-the associated RGBA color is (1, 1, 1, 1),
-the associated color index is 1,
-and the associated texture coordinates are (0, 0, 0, 1).
-In RGBA mode,
-\%\f3GL_CURRENT_RASTER_INDEX\fP is always 1;
-in color index mode,
-the current raster RGBA color always maintains its initial value.
-.SH NOTES
-The raster position is modified both by \%\f3glRasterPos\fP and by \%\f3glBitmap\fP. 
-.P
-When the raster position coordinates are invalid,
-drawing commands that are based on the raster position are
-ignored (that is, they do not result in changes to GL state).
-.P
-Calling \%\f3glDrawElements\fP, or \%\f3glDrawRangeElements\fP may leave the
-current color or index indeterminate.
-If \%\f3glRasterPos\fP is executed while the current color or index is indeterminate, the
-current raster color or current raster index remains indeterminate.
-.P
-To set a valid raster position outside the viewport, first set a valid
-raster position, then call \%\f3glBitmap\fP with NULL as the \f2bitmap\fP
-parameter.
-.P
-When the \%\f3GL_ARB_imaging\fP extension is supported, there are distinct
-raster texture coordinates for each texture unit. Each texture unit's
-current raster texture coordinates are updated by \%\f3glRasterPos\fP.
-.SH ERRORS
-\%\f3GL_INVALID_OPERATION\fP is generated if \%\f3glRasterPos\fP

-.SH DESCRIPTION
-\%\f3glReadPixels\fP returns pixel data from the frame buffer,
-starting with the pixel whose lower left corner
-is at location (\f2x\fP, \f2y\fP),
-into client memory starting at location \f2pixels\fP.
-Several parameters control the processing of the pixel data before
-it is placed into client memory.
-These parameters are set with three commands:
-\%\f3glPixelStore\fP,
-\%\f3glPixelTransfer\fP, and
-\%\f3glPixelMap\fP.
-This reference page describes the effects on \%\f3glReadPixels\fP of most,
-but not all of the parameters specified by these three commands.
-.P
-When the \%\f3GL_ARB_imaging\fP extension is supported, the pixel data may
-be processed by additional operations including color table lookup,
-color matrix transformations, convolutions, histograms and minimum and
-maximun pixel value computations.
-.P
-\%\f3glReadPixels\fP returns values from each pixel with lower left corner at
-(\f2x\fP + $i$, \f2y\fP + $j$) for 0 \(<= $i$ < \f2width\fP and 
-0 \(<= $j$ < \f2height\fP.
-This pixel is said to be the $i$th pixel in the $j$th row. 
-Pixels are returned in row order from the lowest to the highest row,
-left to right in each row.
-.P
-\f2format\fP specifies the  for the returned pixel values;
-accepted values are:
-.TP 10
-\%\f3GL_COLOR_INDEX\fP
-Color indices are read from the color buffer
-selected by \%\f3glReadBuffer\fP.
-Each index is converted to fixed point,
-shifted left or right depending on the value and sign of \%\f3GL_INDEX_SHIFT\fP,
-and added to \%\f3GL_INDEX_OFFSET\fP. 
-If \%\f3GL_MAP_COLOR\fP is \%\f3GL_TRUE\fP,
-indices are replaced by their mappings in the table \%\f3GL_PIXEL_MAP_I_TO_I\fP.
-.TP
-\%\f3GL_STENCIL_INDEX\fP
-Stencil values are read from the stencil buffer.
-Each index is converted to fixed point,
-shifted left or right depending on the value and sign of \%\f3GL_INDEX_SHIFT\fP,
-and added to \%\f3GL_INDEX_OFFSET\fP. 
-If \%\f3GL_MAP_STENCIL\fP is \%\f3GL_TRUE\fP,
-indices are replaced by their mappings in the table \%\f3GL_PIXEL_MAP_S_TO_S\fP.
-.TP
-\%\f3GL_DEPTH_COMPONENT\fP
-Depth values are read from the depth buffer.
-Each component is converted to floating point such that the minimum depth
-value maps to 0 and the maximum value maps to 1.
-Each component is then multiplied by \%\f3GL_DEPTH_SCALE\fP,
-added to \%\f3GL_DEPTH_BIAS\fP,

-Processing differs depending on whether color buffers store color indices
-or RGBA color components.
-If color indices are stored,
-they are read from the color buffer selected by \%\f3glReadBuffer\fP.
-Each index is converted to fixed point,
-shifted left or right depending on the value and sign of \%\f3GL_INDEX_SHIFT\fP,
-and added to \%\f3GL_INDEX_OFFSET\fP. 
-Indices are then replaced by the red,
-green,
-blue,
-and alpha values obtained by indexing the tables
-\%\f3GL_PIXEL_MAP_I_TO_R\fP,
-\%\f3GL_PIXEL_MAP_I_TO_G\fP,
-\%\f3GL_PIXEL_MAP_I_TO_B\fP, and
-\%\f3GL_PIXEL_MAP_I_TO_A\fP.
-Each table must be of size $2 sup n$, but $n$ may be different for 
-different tables. 
-Before an index is used to look up a value in a table of
-size $2 sup n$, it must be masked against $2 sup n - 1$.
-.IP
-If RGBA color components are stored in the color buffers,
-they are read from the color buffer selected by \%\f3glReadBuffer\fP.
-Each color component is converted to floating point such that zero intensity
-maps to 0.0 and full intensity maps to 1.0.
-Each component is then multiplied by \%\f3GL_c_SCALE\fP and
-added to \%\f3GL_c_BIAS\fP,
-where \f2c\fP is RED, GREEN, BLUE, or ALPHA. 
-Finally,
-if \%\f3GL_MAP_COLOR\fP is \%\f3GL_TRUE\fP,
-each component is clamped to the range [0,\ 1],
-scaled to the size of its corresponding table, and is then 
-replaced by its mapping in the table
-\%\f3GL_PIXEL_MAP_c_TO_c\fP,
-where \f2c\fP is R, G, B, or A.
-.IP
-Unneeded data is then discarded.
-For example,
-\%\f3GL_RED\fP discards the green, blue, and alpha components,
-while \%\f3GL_RGB\fP discards only the alpha component.
-\%\f3GL_LUMINANCE\fP computes a single-component value as the sum of
-the red,
-green,
-and blue components,
-and \%\f3GL_LUMINANCE_ALPHA\fP does the same,
-while keeping alpha as a second value.
-The final values are clamped to the range [0,\ 1].
-.P
-The shift,
-scale,
-bias,
-and lookup factors just described are all specified by 
-.br
-\%\f3glPixelTransfer\fP.
-The lookup table contents themselves are specified by \%\f3glPixelMap\fP.
-.P 
-Finally, the indices or components
-are converted to the proper ,
-as specified by \f2type\fP.
-If \f2format\fP is \%\f3GL_COLOR_INDEX\fP or \%\f3GL_STENCIL_INDEX\fP
-and \f2type\fP is not \%\f3GL_FLOAT\fP,
-each index is masked with the mask value given in the following table.
-If \f2type\fP is \%\f3GL_FLOAT\fP, then each integer index is converted to
-single-precision floating-point .
-.P 
-If \f2format\fP is
-\%\f3GL_RED\fP,
-\%\f3GL_GREEN\fP,
-\%\f3GL_BLUE\fP,
-\%\f3GL_ALPHA\fP,
-\%\f3GL_RGB\fP,

-\%\f3GL_RGBA\fP,
-\%\f3GL_BGRA\fP,
-\%\f3GL_LUMINANCE\fP, or
-\%\f3GL_LUMINANCE_ALPHA\fP and \f2type\fP is not \%\f3GL_FLOAT\fP,
-each component is multiplied by the multiplier shown in the following table.
-If type is \%\f3GL_FLOAT\fP, then each component is passed as is

-\f2size\fP
-Specifies the size of \f2buffer\fP.
-.TP
-\f2buffer\fP
-Returns the selection data.
-.SH DESCRIPTION
-\%\f3glSelectBuffer\fP has two arguments:
-\f2buffer\fP is a pointer to an array of unsigned integers,
-and \f2size\fP indicates the size of the array.
-\f2buffer\fP returns values from the name stack
-(see \%\f3glInitNames\fP, \%\f3glLoadName\fP, \%\f3glPushName\fP)
-when the rendering mode is \%\f3GL_SELECT\fP (see \%\f3glRenderMode\fP).
-\%\f3glSelectBuffer\fP must be issued before selection mode is enabled,
-and it must not be issued while the rendering mode is \%\f3GL_SELECT\fP.
-.P
-A programmer can use selection to determine which primitives
-are drawn into some region of a window.
-The region is defined by the current modelview and perspective matrices. 
-.P
-In selection mode, no pixel fragments are produced from rasterization.
-Instead,
-if a primitive or a raster position intersects the clipping 
-volume defined by the viewing frustum
-and the user-defined clipping planes,
-this primitive causes a selection hit.
-(With polygons, no hit occurs if the polygon is culled.)
-When a change is made to the name stack,
-or when \%\f3glRenderMode\fP is called,
-a hit record is copied to \f2buffer\fP if any hits have occurred since the
-last such event
-(name stack change or 
-\%\f3glRenderMode\fP call).
-The hit record consists of the number of names in the name stack at the
-time of the event, followed by the minimum and maximum depth values
-of all vertices that hit since the previous event,
-followed by the name stack contents,
-bottom name first.
-.P
-Depth values (which are in the range [0,1]) are multiplied by 2^32 - 1,
-before being placed in the hit record.
-.P
-An internal index into \f2buffer\fP is reset to 0 whenever selection mode
-is entered.
-Each time a hit record is copied into \f2buffer\fP,
-the index is incremented to point to the cell just past the end
-of the block of names \- that is, to the next available cell.
-If the hit record is larger than the number of remaining locations in \f2buffer\fP,
-as much data as can fit is copied,
-and the overflow flag is set.
-If the name stack is empty when a hit record is copied,
-that record consists of 0 followed by the minimum and maximum depth values.
-.P
-To exit selection mode, call \%\f3glRenderMode\fP with an argument
-other than \%\f3GL_SELECT\fP.
-Whenever \%\f3glRenderMode\fP is called while the render mode is \%\f3GL_SELECT\fP,
-it returns the number of hit records copied to \f2buffer\fP,
-resets the overflow flag and the selection buffer pointer,
-and initializes the name stack to be empty.
-If the overflow bit was set when \%\f3glRenderMode\fP was called,
-a negative hit record count is returned.
-.SH NOTES
-The contents of \f2buffer\fP is undefined until \%\f3glRenderMode\fP is called
-with an argument other than \%\f3GL_SELECT\fP.
-.P
-\%\f3glBegin\fP/\%\f3glEnd\fP primitives and calls to \%\f3glRasterPos\fP
-can result in hits.
-.SH ERRORS
-\%\f3GL_INVALID_VALUE\fP is generated if \f2size\fP is negative.

-.SH DESCRIPTION
-\%\f3glSeparableFilter2D\fP builds a two-dimensional separable convolution filter kernel from
-two arrays of pixels.
-.sp
-The pixel arrays specified by (\f2width\fP, \f2format\fP, \f2type\fP, \f2row\fP)
-and (\f2height\fP, \f2format\fP, \f2type\fP, \f2column\fP) are processed just as if
-they had been passed to \%\f3glDrawPixels\fP,
-but processing stops after the final expansion to RGBA is completed.
-.sp
-Next, the R, G, B, and A components of all pixels in both arrays are scaled
-by the four separable 2D \%\f3GL_CONVOLUTION_FILTER_SCALE\fP parameters and
-biased by the four separable 2D \%\f3GL_CONVOLUTION_FILTER_BIAS\fP parameters.
-(The scale and bias parameters are set by \%\f3glConvolutionParameter\fP
-using the \%\f3GL_SEPARABLE_2D\fP target and the names
-\%\f3GL_CONVOLUTION_FILTER_SCALE\fP and \%\f3GL_CONVOLUTION_FILTER_BIAS\fP.
-The parameters themselves are vectors of four values that are applied to red,
-green, blue, and alpha, in that order.)
-The R, G, B, and A values are not clamped to [0,1] at any time during this
-process.
-.sp
-Each pixel is then converted to the internal  specified by
-\f2internalformat\fP.
-This conversion simply maps the component values of the pixel (R, G, B,
-and A) to the values included in the internal  (red, green, blue,
-alpha, luminance, and intensity).  The mapping is as follows:
-.bp
-.TS
-center;
-l c c c c c c.
-_
-Internal Format	Red	Green	Blue	Alpha	Luminance	Intensity
-_
-\%\f3GL_LUMINANCE\fP					R
-\%\f3GL_LUMINANCE_ALPHA\fP				A	R
-\%\f3GL_INTENSITY\fP						R
-\%\f3GL_RGB\fP	R	G	B
-\%\f3GL_RGBA\fP	R	G	B	A
-_
-.TE
-
-.sp
-The red, green, blue, alpha, luminance, and/or intensity components of
-the resulting pixels are stored in floating-point rather than integer
-.
-They form two one-dimensional filter kernel images.
-The row image is indexed by coordinate \f2i\fP starting at zero and
-increasing from left to right.
-Each location in the row image is derived from element \f2i\fP of \f2row\fP.
-The column image is indexed by coordinate \f2j\fP starting at zero
-and increasing from bottom to top.
-Each location in the column image is derived from element \f2j\fP of \f2column\fP.
-.PP
-Note that after a convolution is performed, the resulting color
-components are also scaled by their corresponding
-\%\f3GL_POST_CONVOLUTION_c_SCALE\fP parameters and biased by their
-corresponding \%\f3GL_POST_CONVOLUTION_c_BIAS\fP parameters (where
-\f2c\fP takes on the values \f3RED\fP, \f3GREEN\fP, \f3BLUE\fP, and
-\f3ALPHA\fP).
-These parameters are set by \%\f3glPixelTransfer\fP.

-The initial value is \%\f3GL_SMOOTH\fP.
-.SH DESCRIPTION
-GL primitives can have either flat or smooth shading.
-Smooth shading,
-the default,
-causes the computed colors of vertices to be interpolated as the
-primitive is rasterized,
-typically assigning different colors to each resulting pixel fragment.
-Flat shading selects the computed color of just one vertex
-and assigns it to all the pixel fragments
-generated by rasterizing a single primitive.
-In either case, the computed color of a vertex is the result of
-lighting if lighting is enabled,
-or it is the current color at the time the vertex was specified if
-lighting is disabled. 
-.P
-Flat and smooth shading are indistinguishable for points.
-Starting when \%\f3glBegin\fP is issued and counting vertices and
-primitives from 1, the GL gives each flat-shaded line segment $i$ the
-computed color of vertex $i ~+~ 1$, its second vertex.
-Counting similarly from 1,
-the GL gives each flat-shaded polygon the computed color of the vertex listed
-in the following table.
-This is the last vertex to specify the polygon in all cases except single
-polygons,
-where the first vertex specifies the flat-shaded color.

-\f2v\fP
-Specifies a pointer to an array of one, two, three, or four elements,
-which in turn specify the
-\f2s\fP,

-\f2r\fP, and
-\f2q\fP texture coordinates.
-.SH DESCRIPTION
-\%\f3glTexCoord\fP specifies texture coordinates in
-one,
-two,
-three, or
-four dimensions.  
-\%\f3glTexCoord1\fP sets the current texture coordinates to
-(\f2s\fP, 0, 0, 1);
-a call to 
-.br
-\%\f3glTexCoord2\fP sets them to
-(\f2s\fP, \f2t\fP, 0, 1).
-.BP
-Similarly, \%\f3glTexCoord3\fP specifies the texture coordinates as
-(\f2s\fP, \f2t\fP, \f2r\fP, 1), and
-\%\f3glTexCoord4\fP defines all four components explicitly as
-(\f2s\fP, \f2t\fP, \f2r\fP, \f2q\fP). 
-.P
-The current texture coordinates are part of the data
-that is associated with each vertex and with the current

-Initially, the values for 
-\f2s\fP,
-\f2t\fP,
-\f2r\fP, and
-\f2q\fP
-are (0, 0, 0, 1). 
-.P
-.SH NOTES
-The current texture coordinates can be updated at any time.
-In particular,
-\%\f3glTexCoord\fP can be called between a call to \%\f3glBegin\fP and the corresponding
-call to \%\f3glEnd\fP.
-.P
-When the \%\f3GL_ARB_imaging\fP extension is supported, \%\f3glTexCoord\fP always
-updates texture unit \%\f3GL_TEXTURE0_ARB\fP.

-.SH DESCRIPTION
-\%\f3glTexCoordPointer\fP specifies the location and data  of an array of texture
-coordinates to use when rendering.
-\f2size\fP specifies the number of coordinates per
-element, and must be 1, 2, 3, or 4.
-\f2type\fP specifies the data type of each texture coordinate
-and \f2stride\fP specifies the byte stride from one
-array element to the next allowing vertices and attributes
-to be packed into a single array or stored in separate arrays.
-(Single-array storage may be more efficient on some implementations;

-.br
-\%\f3glInterleavedArrays\fP.)
-When a texture

-To enable and disable the texture coordinate array, call

-.SH NOTES
-\%\f3glTexCoordPointer\fP is available only if the GL version is 1.1 or greater.

-.P
-Execution of \%\f3glTexCoordPointer\fP is not allowed between the execution of
-\%\f3glBegin\fP and the corresponding execution of \%\f3glEnd\fP,
-but an error may or may not be generated. If no error is generated,
-the operation is undefined.
-.P
-\%\f3glTexCoordPointer\fP is typically implemented on the client side with no protocol.
-.P
-The texture coordinate array parameters are client-side state and are
-therefore not saved or restored by \%\f3glPushAttrib\fP and \%\f3glPopAttrib\fP.
-Use \%\f3glPushClientAttrib\fP and

-.SH DESCRIPTION
-A texture environment specifies how texture values are interpreted
-when a fragment is textured.
-\f2target\fP must be \%\f3GL_TEXTURE_ENV\fP.
-\f2pname\fP can be either \%\f3GL_TEXTURE_ENV_MODE\fP or \%\f3GL_TEXTURE_ENV_COLOR\fP.
-.P
-If \f2pname\fP is \%\f3GL_TEXTURE_ENV_MODE\fP,
-then \f2params\fP is (or points to) the symbolic name of a texture function.
-Four texture functions may be specified:
-\%\f3GL_MODULATE\fP, 
-\%\f3GL_DECAL\fP, 
-\%\f3GL_BLEND\fP, and
-\%\f3GL_REPLACE\fP.
-.P
-A texture function acts on the fragment to be textured using
-the texture image value that applies to the fragment
-(see \%\f3glTexParameter\fP)
-and produces an RGBA color for that fragment.
-The following table shows how the RGBA color is produced for each
-of the three texture functions that can be chosen.
-$C$ is a triple of color values (RGB) and $A$ is the associated alpha value.
-RGBA values extracted from a texture image are in the range [0,1].
-The subscript $f$ refers to the incoming fragment,
-the subscript $t$ to the texture image,
-the subscript $c$ to the texture environment color,
-and subscript $v$ indicates a value produced by the texture function.
-.P
-A texture image can have up to four components per texture element
-(see \%\f3glTexImage1D\fP, \%\f3glTexImage2D\fP, \%\f3glTexImage3D\fP,
-\%\f3glCopyTexImage1D\fP, and \%\f3glCopyTexImage2D\fP). 
-In a one-component image,
-$L sub t$ indicates that single component.
-A two-component image uses $L sub t$ and $A sub t$.
-A three-component image has only a color value, $C sub t$.
-A four-component image has both a color value $C sub t$
-and an alpha value $A sub t$.

-.SH DESCRIPTION
-\%\f3glTexGen\fP selects a texture-coordinate generation function
-or supplies coefficients for one of the functions.
-\f2coord\fP names one of the (\f2s\fP, \f2t\fP, \f2r\fP, \f2q\fP) texture
-coordinates; it must be one of the symbols
-\%\f3GL_S\fP,
-\%\f3GL_T\fP,
-\%\f3GL_R\fP, or
-\%\f3GL_Q\fP.
-\f2pname\fP must be one of three symbolic constants:
-\%\f3GL_TEXTURE_GEN_MODE\fP,
-\%\f3GL_OBJECT_PLANE\fP, or
-\%\f3GL_EYE_PLANE\fP. 
-If \f2pname\fP is \%\f3GL_TEXTURE_GEN_MODE\fP,
-then \f2params\fP chooses a mode,
-one of
-\%\f3GL_OBJECT_LINEAR\fP,
-\%\f3GL_EYE_LINEAR\fP, or
-\%\f3GL_SPHERE_MAP\fP. 
-If \f2pname\fP is either \%\f3GL_OBJECT_PLANE\fP or \%\f3GL_EYE_PLANE\fP,
-\f2params\fP contains coefficients for the corresponding
-texture generation function.
-.P 
-If the texture generation function is \%\f3GL_OBJECT_LINEAR\fP,
-the function
-.P
-.ce
-$g ~=~ p sub 1^x sub o ~+~ p sub 2^y sub o ~+~ p sub 3^z sub o ~+~ p sub 4^w sub o$
-.P
-.br
-is used, where $g$ is the value computed for the coordinate named in \f2coord\fP,
-$p sub 1$,
-$p sub 2$,
-$p sub 3$,
-and
-$p sub 4$ are the four values supplied in \f2params\fP, and
-$x sub o$,
-$y sub o$,
-$z sub o$, and
-$w sub o$ are the object coordinates of the vertex.
-This function can be used, for example, to texture-map terrain using sea level
-as a reference plane
-(defined by $p sub 1$, $p sub 2$, $p sub 3$, and $p sub 4$). 
-The altitude of a terrain vertex is computed by the \%\f3GL_OBJECT_LINEAR\fP
-coordinate generation function as its distance from sea level; 
-that altitude can then be used to index the texture image to map white snow
-onto peaks and green grass onto foothills.
-.P
-If the texture generation function is \%\f3GL_EYE_LINEAR\fP, the function
-.P
-.ce
-$g ~=~ p sub 1 sup prime ^x sub e ~+~ p sub 2 sup prime ^y sub e ~+~ p sub 3 sup prime ^z sub e ~+~ p sub 4 sup prime ^w sub e$
-.P
-.br
-is used, where 
-.P
-.ce
-$( p sub 1 sup prime
-~~p sub 2 sup prime~~p sub 3 sup prime~~
-{ p sub 4 sup prime}) ~=~ ( p sub 1~~ p sub 2~~ p sub 3~~ p sub 4 ) ~M sup -1$
-.P
-.br
-and
-$x sub e$,
-$y sub e$,
-$z sub e$, and
-$w sub e$ are the eye coordinates of the vertex,
-$p sub 1$,
-$p sub 2$,
-$p sub 3$,
-and
-$p sub 4$ are the values supplied in \f2params\fP, and
-$M$ is the modelview matrix when \%\f3glTexGen\fP is invoked.
-If $M$ is poorly conditioned or singular,
-texture coordinates generated by the resulting function may be inaccurate
-or undefined.
-.P
-Note that the values in \f2params\fP define a reference plane in eye coordinates. 
-The modelview matrix that is applied to them may not be the same one
-in effect when the polygon vertices are transformed. 
-This function establishes a field of texture coordinates
-that can produce dynamic contour lines on moving objects.
-.P
-If \f2pname\fP is \%\f3GL_SPHERE_MAP\fP and \f2coord\fP is either
-\%\f3GL_S\fP or
-\%\f3GL_T\fP,
-$s$ and $t$ texture coordinates are generated as follows. 
-Let \f2u\fP be the unit vector pointing from the origin to the polygon vertex
-(in eye coordinates). 
-Let \f2n\fP sup prime be the current normal,
-after transformation to eye coordinates. 
-Let 
-.P
-.ce
-$f ~=~ ( f sub x~~f sub y~~f sub z ) sup T$
-be the reflection vector such that
-.P
-.ce
-$f ~=~  u ~-~ 2 n sup prime n sup prime sup T u$
-.br
-.P
-Finally, let $ m ~=~ 2 sqrt { f sub x sup {~2} ~+~ f sub y sup {~2} ~+~ (f sub z ~+~ 1 ) sup 2}$. 
-Then the values assigned to the $s$ and $t$ texture coordinates are
-.P
-.ce 1
-$s ~=~ f sub x over m ~+~ 1 over 2$
-.sp
-.ce 1
-$t ~=~ f sub y over m ~+~ 1 over 2$
-.P
-To enable or disable a texture-coordinate generation function, call
-\%\f3glEnable\fP or \%\f3glDisable\fP
-with one of the symbolic texture-coordinate names
-(\%\f3GL_TEXTURE_GEN_S\fP,
-\%\f3GL_TEXTURE_GEN_T\fP,
-\%\f3GL_TEXTURE_GEN_R\fP, or
-\%\f3GL_TEXTURE_GEN_Q\fP) as the argument. 
-When enabled,
-the specified texture coordinate is computed
-according to the generating function associated with that coordinate. 
-When disabled,
-subsequent vertices take the specified texture coordinate
-from the current set of texture coordinates. Initially, all texture
-generation functions are set to \%\f3GL_EYE_LINEAR\fP and are disabled.
-Both $s$ plane equations are (1, 0, 0, 0),
-both $t$ plane equations are (0, 1, 0, 0),
-and all $r$ and $q$ plane equations are (0, 0, 0, 0).
-.P
-When the \%\f3GL_ARB_multitexture\fP extension is supported, \%\f3glTexGen\fP set the
-texture generation parameters for the currently active texture unit,
-selected with \%\f3glActiveTextureARB\fP.
-.SH ERRORS
-\%\f3GL_INVALID_ENUM\fP is generated when \f2coord\fP or \f2pname\fP is not an
-accepted defined value,
-or when \f2pname\fP is \%\f3GL_TEXTURE_GEN_MODE\fP and \f2params\fP is not an

-\f2pixels\fP
-Specifies a pointer to the image data in memory.
-.SH DESCRIPTION
-Texturing maps a portion of a specified texture image
-onto each graphical primitive for which texturing is enabled.
-To enable and disable one-dimensional texturing, call \%\f3glEnable\fP
-and \%\f3glDisable\fP with argument \%\f3GL_TEXTURE_1D\fP.
-.P
-Texture images are defined with \%\f3glTexImage1D\fP.
-The arguments describe the parameters of the texture image,
-such as width,
-width of the border,
-level-of-detail number
-(see \%\f3glTexParameter\fP),
-and the internal resolution and  used to store the image.
-The last three arguments describe how the image is represented in
-memory; they are identical to the pixel formats used for
-\%\f3glDrawPixels\fP. 
-.P
-If \f2target\fP is \%\f3GL_PROXY_TEXTURE_1D\fP, no data is read from \f2pixels\fP, but
-all of the texture image state is recalculated, checked for
-consistency, and checked against the implementation's capabilities.
-If the implementation cannot handle a texture of the
-requested texture size, it sets all of the image state to 0,
-but does not generate an error (see \%\f3glGetError\fP). To query for an
-entire mipmap array, use an image array level greater than or equal to
-1. 
-.P
-If \f2target\fP is \%\f3GL_TEXTURE_1D\fP,
-data is read from \f2pixels\fP as a sequence of signed or unsigned bytes,
-shorts,
-or longs,
-or single-precision floating-point values,
-depending on \f2type\fP. 
-These values are grouped into sets of one,
-two,
-three,
-or four values,
-depending on \f2format\fP,
-to form elements. 
-If \f2type\fP is \%\f3GL_BITMAP\fP,
-the data is considered as a string of unsigned bytes
-(and \f2format\fP must be \%\f3GL_COLOR_INDEX\fP). 
-Each data byte is treated as eight 1-bit elements,
-with bit ordering determined by \%\f3GL_UNPACK_LSB_FIRST\fP
-(see \%\f3glPixelStore\fP).
-.P
-The first element corresponds to the left end of the texture array.
-Subsequent elements progress left-to-right through the remaining texels
-in the texture array.
-The final element corresponds to the right end of the texture array.
-.P
-\f2format\fP determines the composition of each element in \f2pixels\fP.
-It can assume one of eleven symbolic values:
-.TP 10
-\%\f3GL_COLOR_INDEX\fP
-Each element is a single value,
-a color index. 
-The GL converts it to fixed point
-(with an unspecified number of zero bits to the right of the binary point),
-shifted left or right depending on the value and sign of \%\f3GL_INDEX_SHIFT\fP,
-and added to \%\f3GL_INDEX_OFFSET\fP
-(see \%\f3glPixelTransfer\fP). 
-The resulting index is converted to a set of color components
-using the
-\%\f3GL_PIXEL_MAP_I_TO_R\fP,
-\%\f3GL_PIXEL_MAP_I_TO_G\fP,
-\%\f3GL_PIXEL_MAP_I_TO_B\fP, and
-\%\f3GL_PIXEL_MAP_I_TO_A\fP tables,
-and clamped to the range [0,1].
-.TP
-\%\f3GL_RED\fP
-Each element is a single red component. 
-The GL converts it to floating point and assembles it into an RGBA element
-by attaching 0 for green and blue, and 1 for alpha. 
-Each component is then multiplied by the signed scale factor \%\f3GL_c_SCALE\fP,
-added to the signed bias \%\f3GL_c_BIAS\fP.  
-and clamped to the range [0,1]
-(see \%\f3glPixelTransfer\fP).
-.TP
-\%\f3GL_GREEN\fP
-Each element is a single green component. 
-The GL converts it to floating point and assembles it into an RGBA element
-by attaching 0 for red and blue, and 1 for alpha. 
-Each component is then multiplied by the signed scale factor \%\f3GL_c_SCALE\fP,
-added to the signed bias \%\f3GL_c_BIAS\fP,
-and clamped to the range [0,1]
-(see \%\f3glPixelTransfer\fP).
-.TP
-\%\f3GL_BLUE\fP
-Each element is a single blue component. 
-The GL converts it to floating point and assembles it into an RGBA element
-by attaching 0 for red and green, and 1 for alpha. 
-Each component is then multiplied by the signed scale factor \%\f3GL_c_SCALE\fP,
-added to the signed bias \%\f3GL_c_BIAS\fP,
-and clamped to the range [0,1]
-(see \%\f3glPixelTransfer\fP).
-.TP
-\%\f3GL_ALPHA\fP
-Each element is a single alpha component. 
-The GL converts it to floating point and assembles it into an RGBA element
-by attaching 0 for red, green, and blue.
-Each component is then multiplied by the signed scale factor \%\f3GL_c_SCALE\fP,
-added to the signed bias \%\f3GL_c_BIAS\fP,
-and clamped to the range [0,1]
-(see \%\f3glPixelTransfer\fP).
-.TP
-\%\f3GL_RGB\fP
-.TP
-\%\f3GL_BGR\fP
-Each element is an RGB triple.
-The GL converts it to floating point and assembles it into an RGBA element
-by attaching 1 for alpha.
-Each component is then multiplied by the signed scale factor \%\f3GL_c_SCALE\fP,
-added to the signed bias \%\f3GL_c_BIAS\fP,
-and clamped to the range [0,1]
-(see \%\f3glPixelTransfer\fP).
-.TP
-\%\f3GL_RGBA\fP
-.TP
-\%\f3GL_BGRA\fP
-Each element contains all four components.
-Each component is then multiplied by the signed scale factor \%\f3GL_c_SCALE\fP,
-added to the signed bias \%\f3GL_c_BIAS\fP,
-and clamped to the range [0,1]
-(see \%\f3glPixelTransfer\fP).
-.TP
-\%\f3GL_LUMINANCE\fP
-Each element is a single luminance value.
-The GL converts it to floating point,
-then assembles it into an RGBA element by replicating the luminance value
-three times for red, green, and blue and attaching 1 for alpha. 
-Each component is then multiplied by the signed scale factor \%\f3GL_c_SCALE\fP,
-added to the signed bias \%\f3GL_c_BIAS\fP,
-and clamped to the range [0,1]
-(see \%\f3glPixelTransfer\fP).
-.TP
-\%\f3GL_LUMINANCE_ALPHA\fP
-Each element is a luminance/alpha pair.
-The GL converts it to floating point,
-then assembles it into an RGBA element by replicating the luminance value
-three times for red, green, and blue.
-Each component is then multiplied by the signed scale factor \%\f3GL_c_SCALE\fP,
-added to the signed bias \%\f3GL_c_BIAS\fP,
-and clamped to the range [0,1] (see \%\f3glPixelTransfer\fP).
-.P
-If an application wants to store the texture at a certain
-resolution or in a certain , it can request the resolution
-and  with \f2internalFormat\fP. The GL will choose an internal
-representation that closely approximates that requested by \f2internalFormat\fP, but
-it may not match exactly.
-(The representations specified by \%\f3GL_LUMINANCE\fP, \%\f3GL_LUMINANCE_ALPHA\fP, \%\f3GL_RGB\fP,
-and \%\f3GL_RGBA\fP must match exactly. The numeric values 1, 2, 3, and 4 may also be used to 
-specify the preceding representations.)
-.P
-Use the \%\f3GL_PROXY_TEXTURE_1D\fP target to try out a resolution and
-. The implementation will
-update and recompute its best match for the requested storage resolution
-and . To query this state, call \%\f3glGetTexLevelParameter\fP.
-If the texture cannot be accommodated, texture state is set to 0.
-.P
-A one-component texture image uses only the red component of the RGBA
-color from \f2pixels\fP. 
-A two-component image uses the R and A values.
-A three-component image uses the R, G, and B values.
-A four-component image uses all of the RGBA components. 
-.SH NOTES
-Texturing has no effect in color index mode.
-.P
-If the \%\f3GL_ARB_imaging\fP extension is supported, RGBA elements may
-also be processed by the imaging pipeline.  The following stages may be
-applied to an RGBA color before color component clamping to the range
-[0,\ 1]:
-.TP 3
-1. Color component replacement by the color table specified for
-\%\f3GL_COLOR_TABLE\fP, if enabled. See \%\f3glColorTable\fP.
-.TP
-2. One-dimensional convolution filtering, if enabled. See
-\%\f3glConvolutionFilter1D\fP.
-.IP
-If a convolution filter changes the __width of the texture (by
-processing with a \%\f3GL_CONVOLUTION_BORDER_MODE\fP of \%\f3GL_REDUCE\fP, for 
-example), the \f2width\fP must $2 sup n + 2 ( "border" )$, for some
-integer $n$, after filtering.
-.TP
-3. RGBA components may be multiplied by \%\f3GL_POST_CONVOLUTION_c_SCALE\fP, 
-and added to \%\f3GL_POST_CONVOLUTION_c_BIAS\fP, if enabled.  See 
-\%\f3glPixelTransfer\fP.

-4. Color component replacement by the color table specified for
-\%\f3GL_POST_CONVOLUTION_COLOR_TABLE\fP, if enabled.  See \%\f3glColorTable\fP.

-5. Transformation by the color matrix.  See \%\f3glMatrixMode\fP.
-.TP
-6. RGBA components may be multiplied by \%\f3GL_POST_COLOR_MATRIX_c_SCALE\fP,

-The texture image can be represented by the same data formats
-as the pixels in a \%\f3glDrawPixels\fP command,
-except that \%\f3GL_STENCIL_INDEX\fP and \%\f3GL_DEPTH_COMPONENT\fP

-.TP
-\f2pixels\fP
-Specifies a pointer to the image data in memory.
-.SH DESCRIPTION
-Texturing maps a portion of a specified texture image
-onto each graphical primitive for which texturing is enabled.
-To enable and disable two-dimensional texturing, call \%\f3glEnable\fP
-and \%\f3glDisable\fP with argument \%\f3GL_TEXTURE_2D\fP.
-.P
-To define texture images, call \%\f3glTexImage2D\fP. 
-The arguments describe the parameters of the texture image,
-such as height,
-width,
-width of the border,
-level-of-detail number
-(see \%\f3glTexParameter\fP),
-and number of color components provided.
-The last three arguments describe how the image is represented in memory;
-they are identical to the pixel formats used for \%\f3glDrawPixels\fP.
-.P
-If \f2target\fP is \%\f3GL_PROXY_TEXTURE_2D\fP, no data is read from \f2pixels\fP, but
-all of the texture image state is recalculated, checked for
-consistency, and checked 
-against the implementation's capabilities. If the implementation cannot
-handle a texture of the requested texture size, it sets
-all of the image state to 0,
-but does not generate an error (see \%\f3glGetError\fP). To query for an
-entire mipmap array, use an image array level greater than or equal to
-1. 
-.P 
-If \f2target\fP is \%\f3GL_TEXTURE_2D\fP,
-data is read from \f2pixels\fP as a sequence of signed or unsigned bytes,
-shorts,
-or longs,
-or single-precision floating-point values,
-depending on \f2type\fP. 
-These values are grouped into sets of one,
-two,
-three,
-or four values,
-depending on \f2format\fP,
-to form elements. 
-If \f2type\fP is \%\f3GL_BITMAP\fP,
-the data is considered as a string of unsigned bytes (and
-\f2format\fP must be \%\f3GL_COLOR_INDEX\fP). 
-.bp
-Each data byte is treated as eight 1-bit elements,
-with bit ordering determined by \%\f3GL_UNPACK_LSB_FIRST\fP
-(see \%\f3glPixelStore\fP).
-.P
-The first element corresponds to the lower left corner of the texture
-image.
-Subsequent elements progress left-to-right through the remaining texels
-in the lowest row of the texture image, and then in successively higher
-rows of the texture image.
-The final element corresponds to the upper right corner of the texture
-image.
-.P
-\f2format\fP determines the composition of each element in \f2pixels\fP.
-It can assume one of eleven symbolic values:
-.TP 10
-\%\f3GL_COLOR_INDEX\fP
-Each element is a single value,
-a color index. 
-The GL converts it to fixed point
-(with an unspecified number of zero bits to the right of the binary point),
-shifted left or right depending on the value and sign of \%\f3GL_INDEX_SHIFT\fP,
-and added to \%\f3GL_INDEX_OFFSET\fP
-(see 
-.br
-\%\f3glPixelTransfer\fP). 
-The resulting index is converted to a set of color components
-using the
-\%\f3GL_PIXEL_MAP_I_TO_R\fP,
-\%\f3GL_PIXEL_MAP_I_TO_G\fP,
-\%\f3GL_PIXEL_MAP_I_TO_B\fP, and
-\%\f3GL_PIXEL_MAP_I_TO_A\fP tables,
-and clamped to the range [0,1].
-.TP
-\%\f3GL_RED\fP
-Each element is a single red component. 
-The GL converts it to floating point and assembles it into an RGBA element
-by attaching 0 for green and blue, and 1 for alpha. 
-Each component is then multiplied by the signed scale factor \%\f3GL_c_SCALE\fP,
-added to the signed bias \%\f3GL_c_BIAS\fP,
-and clamped to the range [0,1]
-(see \%\f3glPixelTransfer\fP).
-.TP
-\%\f3GL_GREEN\fP
-Each element is a single green component. 
-The GL converts it to floating point and assembles it into an RGBA element
-by attaching 0 for red and blue, and 1 for alpha. 
-Each component is then multiplied by the signed scale factor \%\f3GL_c_SCALE\fP,
-added to the signed bias \%\f3GL_c_BIAS\fP,
-and clamped to the range [0,1]
-(see \%\f3glPixelTransfer\fP).
-.TP
-\%\f3GL_BLUE\fP
-Each element is a single blue component. 
-The GL converts it to floating point and assembles it into an RGBA element
-by attaching 0 for red and green, and 1 for alpha. 
-Each component is then multiplied by the signed scale factor \%\f3GL_c_SCALE\fP,
-added to the signed bias \%\f3GL_c_BIAS\fP,
-and clamped to the range [0,1]
-(see \%\f3glPixelTransfer\fP).
-.TP
-\%\f3GL_ALPHA\fP
-Each element is a single alpha component. 
-The GL converts it to floating point and assembles it into an RGBA element
-by attaching 0 for red, green, and blue.
-Each component is then multiplied by the signed scale factor \%\f3GL_c_SCALE\fP,
-added to the signed bias \%\f3GL_c_BIAS\fP,
-and clamped to the range [0,1]
-(see \%\f3glPixelTransfer\fP).
-.TP
-\%\f3GL_RGB\fP
-.TP
-\%\f3GL_BGR\fP
-Each element is an RGB triple.
-The GL converts it to floating point and assembles it into an RGBA element
-by attaching 1 for alpha.
-Each component is then multiplied by the signed scale factor \%\f3GL_c_SCALE\fP,
-added to the signed bias \%\f3GL_c_BIAS\fP,
-and clamped to the range [0,1]
-(see 
-.br
-\%\f3glPixelTransfer\fP).
-.TP
-\%\f3GL_RGBA\fP
-.TP
-\%\f3GL_BGRA\fP
-Each element contains all four components.
-Each component is multiplied by the signed scale factor \%\f3GL_c_SCALE\fP,
-added to the signed bias \%\f3GL_c_BIAS\fP,
-and clamped to the range [0,1]
-(see \%\f3glPixelTransfer\fP).
-.TP
-\%\f3GL_LUMINANCE\fP
-Each element is a single luminance value.
-The GL converts it to floating point,
-then assembles it into an RGBA element by replicating the luminance value
-three times for red, green, and blue and attaching 1 for alpha. 
-Each component is then multiplied by the signed scale factor \%\f3GL_c_SCALE\fP,
-added to the signed bias \%\f3GL_c_BIAS\fP,
-and clamped to the range [0,1]
-(see \%\f3glPixelTransfer\fP).
-.TP
-\%\f3GL_LUMINANCE_ALPHA\fP
-Each element is a luminance/alpha pair.
-The GL converts it to floating point,
-then assembles it into an RGBA element by replicating the luminance value
-three times for red, green, and blue.
-Each component is then multiplied by the signed scale factor \%\f3GL_c_SCALE\fP,
-added to the signed bias \%\f3GL_c_BIAS\fP,
-and clamped to the range [0,1]
-(see 
-.br
-\%\f3glPixelTransfer\fP).
-.P
-Refer to the \%\f3glDrawPixels\fP reference page for a description of
-the acceptable values for the \f2type\fP parameter.
-.P
-If an application wants to store the texture at a certain
-resolution or in a certain , it can request the resolution
-and  with \f2internalFormat\fP. The GL will choose an internal
-representation that closely approximates that requested by \f2internalFormat\fP, but
-it may not match exactly.
-(The representations specified by \%\f3GL_LUMINANCE\fP,
-\%\f3GL_LUMINANCE_ALPHA\fP, \%\f3GL_RGB\fP,
-and \%\f3GL_RGBA\fP must match exactly. The numeric values 1, 2, 3, and 4
-may also be used to specify the above representations.)
-.P
-Use the \%\f3GL_PROXY_TEXTURE_2D\fP target to try out a resolution and
-. The implementation will
-update and recompute its best match for the requested storage resolution
-and . To then query this state, call
-\%\f3glGetTexLevelParameter\fP.
-If the texture cannot be accommodated, texture state is set to 0.
-.P
-A one-component texture image uses only the red component of the RGBA
-color extracted from \f2pixels\fP. 
-A two-component image uses the R and A values.
-A three-component image uses the R, G, and B values.
-A four-component image uses all of the RGBA components. 
-.SH NOTES
-Texturing has no effect in color index mode.
-.P
-If the \%\f3GL_ARB_imaging\fP extension is supported, RGBA elements may
-also be processed by the imaging pipeline.  The following stages may be
-applied to an RGBA color before color component clamping to the range
-[0,\ 1]:
-.TP 3
-1. Color component replacement by the color table specified for
-\%\f3GL_COLOR_TABLE\fP, if enabled. See \%\f3glColorTable\fP.
-.TP
-2. Two-dimensional Convolution filtering, if enabled. See
-\%\f3glConvolutionFilter1D\fP.
-.IP
-If a convolution filter changes the __width of the texture (by
-processing with a \%\f3GL_CONVOLUTION_BORDER_MODE\fP of \%\f3GL_REDUCE\fP, for 
-example), the \f2width\fP must $2 sup n + 2 ( "height" )$, for some
-integer $n$, and \f2height\fP must be $2 sup m + ( "border" )$, for some
-integer $m$,  after filtering.
-.TP
-3. RGBA components may be multiplied by \%\f3GL_POST_CONVOLUTION_c_SCALE\fP, 
-and added to \%\f3GL_POST_CONVOLUTION_c_BIAS\fP, if enabled.  See 
-\%\f3glPixelTransfer\fP.
-.TP
-4. Color component replacement by the color table specified for
-\%\f3GL_POST_CONVOLUTION_COLOR_TABLE\fP, if enabled.  See \%\f3glColorTable\fP.
-.TP
-5. Transformation by the color matrix.  See \%\f3glMatrixMode\fP.
-.TP
-6. RGBA components may be multiplied by \%\f3GL_POST_COLOR_MATRIX_c_SCALE\fP, 
-and added to \%\f3GL_POST_COLOR_MATRIX_c_BIAS\fP, if enabled.  See 
-\%\f3glPixelTransfer\fP.
-.TP
-7. Color component replacement by the color table specified for
-\%\f3GL_POST_COLOR_MATRIX_COLOR_TABLE\fP, if enabled.  See
-\%\f3glColorTable\fP.
-.P
-The texture image can be represented by the same data formats
-as the pixels in a \%\f3glDrawPixels\fP command,
-except that \%\f3GL_STENCIL_INDEX\fP and \%\f3GL_DEPTH_COMPONENT\fP
-cannot be used.

-.TP
-\f2pixels\fP
-Specifies a pointer to the image data in memory.
-.SH DESCRIPTION
-Texturing maps a portion of a specified texture image
-onto each graphical primitive for which texturing is enabled.
-To enable and disable three-dimensional texturing, call \%\f3glEnable\fP
-and \%\f3glDisable\fP with argument \%\f3GL_TEXTURE_3D\fP.
-.P
-To define texture images, call \%\f3glTexImage3D\fP. 
-The arguments describe the parameters of the texture image,
-such as height,
-width, depth,
-width of the border,
-level-of-detail number
-(see \%\f3glTexParameter\fP),
-and number of color components provided.
-The last three arguments describe how the image is represented in memory;
-they are identical to the pixel formats used for \%\f3glDrawPixels\fP.
-.P
-If \f2target\fP is \%\f3GL_PROXY_TEXTURE_3D\fP, no data is read from \f2pixels\fP, but
-all of the texture image state is recalculated, checked for
-consistency, and checked 
-against the implementation's capabilities. If the implementation cannot
-handle a texture of the requested texture size, it sets
-all of the image state to 0,
-but does not generate an error (see \%\f3glGetError\fP). To query for an
-entire mipmap array, use an image array level greater than or equal to
-1. 
-.P 
-If \f2target\fP is \%\f3GL_TEXTURE_3D\fP,
-data is read from \f2pixels\fP as a sequence of signed or unsigned bytes,
-shorts,
-or longs,
-or single-precision floating-point values,
-depending on \f2type\fP. 
-These values are grouped into sets of one,
-two,
-three,
-or four values,
-depending on \f2format\fP,
-to form elements. 
-If \f2type\fP is \%\f3GL_BITMAP\fP,
-the data is considered as a string of unsigned bytes (and
-\f2format\fP must be \%\f3GL_COLOR_INDEX\fP). 
-Each data byte is treated as eight 1-bit elements,
-with bit ordering determined by \%\f3GL_UNPACK_LSB_FIRST\fP
-(see \%\f3glPixelStore\fP).
-.P
-The first element corresponds to the lower left corner of the texture
-image.
-Subsequent elements progress left-to-right through the remaining texels
-in the lowest row of the texture image, and then in successively higher
-rows of the texture image.
-The final element corresponds to the upper right corner of the texture
-image.
-.P
-\f2format\fP determines the composition of each element in \f2pixels\fP.
-It can assume one of eleven symbolic values:
-.TP 10
-\%\f3GL_COLOR_INDEX\fP
-Each element is a single value,
-a color index. 
-The GL converts it to fixed point
-(with an unspecified number of zero bits to the right of the binary point),
-shifted left or right depending on the value and sign of \%\f3GL_INDEX_SHIFT\fP,
-and added to \%\f3GL_INDEX_OFFSET\fP
-(see 
-.br
-\%\f3glPixelTransfer\fP). 
-The resulting index is converted to a set of color components
-using the
-\%\f3GL_PIXEL_MAP_I_TO_R\fP,
-\%\f3GL_PIXEL_MAP_I_TO_G\fP,
-\%\f3GL_PIXEL_MAP_I_TO_B\fP, and
-\%\f3GL_PIXEL_MAP_I_TO_A\fP tables,
-and clamped to the range [0,1].
-.TP
-\%\f3GL_RED\fP
-Each element is a single red component. 
-The GL converts it to floating point and assembles it into an RGBA element
-by attaching 0 for green and blue, and 1 for alpha. 
-Each component is then multiplied by the signed scale factor \%\f3GL_c_SCALE\fP,
-added to the signed bias \%\f3GL_c_BIAS\fP,
-and clamped to the range [0,1]
-(see \%\f3glPixelTransfer\fP).
-.TP
-\%\f3GL_GREEN\fP
-Each element is a single green component. 
-The GL converts it to floating point and assembles it into an RGBA element
-by attaching 0 for red and blue, and 1 for alpha. 
-Each component is then multiplied by the signed scale factor \%\f3GL_c_SCALE\fP,
-added to the signed bias \%\f3GL_c_BIAS\fP,
-and clamped to the range [0,1]
-(see \%\f3glPixelTransfer\fP).
-.TP
-\%\f3GL_BLUE\fP
-Each element is a single blue component. 
-The GL converts it to floating point and assembles it into an RGBA element
-by attaching 0 for red and green, and 1 for alpha. 
-Each component is then multiplied by the signed scale factor \%\f3GL_c_SCALE\fP,
-added to the signed bias \%\f3GL_c_BIAS\fP,
-and clamped to the range [0,1]
-(see \%\f3glPixelTransfer\fP).
-.TP
-\%\f3GL_ALPHA\fP
-Each element is a single alpha component. 
-The GL converts it to floating point and assembles it into an RGBA element
-by attaching 0 for red, green, and blue.
-Each component is then multiplied by the signed scale factor \%\f3GL_c_SCALE\fP,
-added to the signed bias \%\f3GL_c_BIAS\fP,
-and clamped to the range [0,1]
-(see \%\f3glPixelTransfer\fP).
-.TP
-\%\f3GL_RGB\fP
-.TP
-\%\f3GL_BGR\fP
-Each element is an RGB triple.
-The GL converts it to floating point and assembles it into an RGBA element
-by attaching 1 for alpha.
-Each component is then multiplied by the signed scale factor \%\f3GL_c_SCALE\fP,
-added to the signed bias \%\f3GL_c_BIAS\fP,
-and clamped to the range [0,1]
-(see 
-.br
-\%\f3glPixelTransfer\fP).
-.TP
-\%\f3GL_RGBA\fP
-.TP
-\%\f3GL_BGRA\fP
-Each element contains all four components.
-Each component is multiplied by the signed scale factor \%\f3GL_c_SCALE\fP,
-added to the signed bias \%\f3GL_c_BIAS\fP,
-and clamped to the range [0,1]
-(see \%\f3glPixelTransfer\fP).
-.TP
-\%\f3GL_LUMINANCE\fP
-Each element is a single luminance value.
-The GL converts it to floating point,
-then assembles it into an RGBA element by replicating the luminance value
-three times for red, green, and blue and attaching 1 for alpha. 
-Each component is then multiplied by the signed scale factor \%\f3GL_c_SCALE\fP,
-added to the signed bias \%\f3GL_c_BIAS\fP,
-and clamped to the range [0,1]
-(see \%\f3glPixelTransfer\fP).
-.TP
-\%\f3GL_LUMINANCE_ALPHA\fP
-Each element is a luminance/alpha pair.
-The GL converts it to floating point,
-then assembles it into an RGBA element by replicating the luminance value
-three times for red, green, and blue.
-Each component is then multiplied by the signed scale factor \%\f3GL_c_SCALE\fP,
-added to the signed bias \%\f3GL_c_BIAS\fP,
-and clamped to the range [0,1]
-(see 
-.br
-\%\f3glPixelTransfer\fP).
-.P
-Refer to the \%\f3glDrawPixels\fP reference page for a description of
-the acceptable values for the \f2type\fP parameter.
-.P
-If an application wants to store the texture at a certain
-resolution or in a certain , it can request the resolution
-and  with \f2internalFormat\fP. The GL will choose an internal
-representation that closely approximates that requested by \f2internalFormat\fP, but
-it may not match exactly.
-(The representations specified by \%\f3GL_LUMINANCE\fP,
-\%\f3GL_LUMINANCE_ALPHA\fP, \%\f3GL_RGB\fP,
-and \%\f3GL_RGBA\fP must match exactly. The numeric values 1, 2, 3, and 4
-may also be used to specify the above representations.)
-.P
-Use the \%\f3GL_PROXY_TEXTURE_3D\fP target to try out a resolution and
-. The implementation will
-update and recompute its best match for the requested storage resolution
-and . To then query this state, call
-\%\f3glGetTexLevelParameter\fP.
-If the texture cannot be accommodated, texture state is set to 0.
-.P
-A one-component texture image uses only the red component of the RGBA
-color extracted from \f2pixels\fP. 
-A two-component image uses the R and A values.
-A three-component image uses the R, G, and B values.
-A four-component image uses all of the RGBA components. 
-.SH NOTES
-Texturing has no effect in color index mode.
-.P
-The texture image can be represented by the same data formats
-as the pixels in a \%\f3glDrawPixels\fP command,
-except that \%\f3GL_STENCIL_INDEX\fP and \%\f3GL_DEPTH_COMPONENT\fP
-cannot be used.
-\%\f3glPixelStore\fP and \%\f3glPixelTransfer\fP modes affect texture images
-in exactly the way they affect \%\f3glDrawPixels\fP.
-.P
-.P
-\%\f3glTexImage3D\fP is available only if the GL version is 1.2 or greater. 
-.P
-Internal formats other than 1, 2, 3, or 4 may be used only if the GL
-version is 1.1 or greater.
-.P
-\f2pixels\fP may be a null pointer. 
-In this case texture memory is
-allocated to accommodate a texture of width \f2width\fP, height \f2height\fP,
-and depth \f2depth\fP.
-You can then download subtextures to initialize this
-texture memory. 
-The image is undefined if the user tries to apply
-an uninitialized portion of the texture image to a primitive.

-If the \%\f3GL_ARB_imaging\fP extension is supported, RGBA elements may

-.SH DESCRIPTION
-Texture mapping is a technique that applies an image onto an object's surface
-as if the image were a decal or cellophane shrink-wrap. 
-The image is created in texture space,
-with an ($s$, $t$) coordinate system. 
-A texture is a one- or two-dimensional image and a set of parameters
-that determine how samples are derived from the image.
-.P
-\%\f3glTexParameter\fP assigns the value or values in \f2params\fP to the texture parameter
-specified as \f2pname\fP. 
-\f2target\fP defines the target texture,
-either \%\f3GL_TEXTURE_1D\fP, \%\f3GL_TEXTURE_2D\fP, or \%\f3GL_TEXTURE_3D\fP.
-The following symbols are accepted in \f2pname\fP:
-.TP 10
-\%\f3GL_TEXTURE_MIN_FILTER\fP
-The texture minifying function is used whenever the pixel being textured
-maps to an area greater than one texture element. 
-There are six defined minifying functions.
-Two of them use the nearest one or nearest four texture elements
-to compute the texture value. 
-The other four use mipmaps.
-.IP
-A mipmap is an ordered set of arrays representing the same image
-at progressively lower resolutions. 
-If the texture has dimensions $2 sup n ~times~ 2 sup m$, there are
-$ bold max ( n, m ) + 1 $ mipmaps. 
-The first mipmap is the original texture,
-with dimensions $2 sup n ~times~ 2 sup m$. 
-Each subsequent mipmap has dimensions $2 sup { k - 1 } ~times~ 2 sup { l - 1 }$,
-where $2 sup k ~times~ 2 sup l$ are the dimensions of the previous mipmap,
-until either $k ~=~ 0$ or $l~=~0$.
-At that point,
-subsequent mipmaps have dimension $ 1 ~times~ 2 sup { l - 1 } $
-or $ 2 sup { k - 1} ~times~ 1 $ until the final mipmap,
-which has dimension $1 ~times~ 1$. 
-To define the mipmaps, call \%\f3glTexImage1D\fP, \%\f3glTexImage2D\fP,
-\%\f3glTexImage3D\fP, 
-\%\f3glCopyTexImage1D\fP, or \%\f3glCopyTexImage2D\fP
-with the \f2level\fP argument indicating the order of the mipmaps.
-Level 0 is the original texture;
-level $ bold max ( n, m ) $ is the final $1 ~times~ 1$ mipmap.
-.IP
-\f2params\fP supplies a function for minifying the texture as one of the following:
-.RS 10
-.TP 10
-\%\f3GL_NEAREST\fP
-Returns the value of the texture element that is nearest
-(in Manhattan distance)
-to the center of the pixel being textured.
-.TP
-\%\f3GL_LINEAR\fP
-Returns the weighted average of the four texture elements
-that are closest to the center of the pixel being textured.
-These can include border texture elements,
-depending on the values of \%\f3GL_TEXTURE_WRAP_S\fP and \%\f3GL_TEXTURE_WRAP_T\fP,
-and on the exact mapping.
-.TP
-\%\f3GL_NEAREST_MIPMAP_NEAREST\fP
-Chooses the mipmap that most closely matches the size of the pixel
-being textured and uses the \%\f3GL_NEAREST\fP criterion
-(the texture element nearest to the center of the pixel)
-to produce a texture value.
-.TP
-\%\f3GL_LINEAR_MIPMAP_NEAREST\fP
-Chooses the mipmap that most closely matches the size of the pixel
-being textured and uses the \%\f3GL_LINEAR\fP criterion
-(a weighted average of the four texture elements that are closest
-to the center of the pixel)
-to produce a texture value.
-.TP
-\%\f3GL_NEAREST_MIPMAP_LINEAR\fP
-Chooses the two mipmaps that most closely match the size of the pixel
-being textured and uses the \%\f3GL_NEAREST\fP criterion
-(the texture element nearest to the center of the pixel)
-to produce a texture value from each mipmap. 
-The final texture value is a weighted average of those two values.
-.TP
-\%\f3GL_LINEAR_MIPMAP_LINEAR\fP
-Chooses the two mipmaps that most closely match the size of the pixel
-being textured and uses the \%\f3GL_LINEAR\fP criterion
-(a weighted average of the four texture elements that are closest
-to the center of the pixel)
-to produce a texture value from each mipmap.
-The final texture value is a weighted average of those two values.
-.RE
-.IP
-As more texture elements are sampled in the minification process,
-fewer aliasing artifacts will be apparent. 
-While the \%\f3GL_NEAREST\fP and \%\f3GL_LINEAR\fP minification functions can be
-faster than the other four,
-they sample only one or four texture elements to determine the texture value
-of the pixel being rendered and can produce moire patterns
-or ragged transitions. 
-The initial value of \%\f3GL_TEXTURE_MIN_FILTER\fP is
-\%\f3GL_NEAREST_MIPMAP_LINEAR\fP.
-.TP 10
-\%\f3GL_TEXTURE_MAG_FILTER\fP
-The texture magnification function is used when the pixel being textured
-maps to an area less than or equal to one texture element.
-It sets the texture magnification function to either \%\f3GL_NEAREST\fP
-or \%\f3GL_LINEAR\fP (see below). \%\f3GL_NEAREST\fP is generally faster
-than \%\f3GL_LINEAR\fP, 
-but it can produce textured images with sharper edges
-because the transition between texture elements is not as smooth. 
-The initial value of \%\f3GL_TEXTURE_MAG_FILTER\fP is \%\f3GL_LINEAR\fP.
-.RS 10
-.TP 10
-\%\f3GL_NEAREST\fP
-Returns the value of the texture element that is nearest
-(in Manhattan distance)
-to the center of the pixel being textured.
-.TP
-\%\f3GL_LINEAR\fP
-Returns the weighted average of the four texture elements
-that are closest to the center of the pixel being textured.
-These can include border texture elements,
-depending on the values of \%\f3GL_TEXTURE_WRAP_S\fP and \%\f3GL_TEXTURE_WRAP_T\fP,
-and on the exact mapping.
-.P
-.RE
-.P
-.TP 10
-\%\f3GL_TEXTURE_MIN_LOD\fP
-Sets the minimum level-of-detail parameter.  This floating-point value
-limits the selection of highest resolution mipmap (lowest mipmap
-level). The initial value is -1000.
-.P
-.TP 10
-\%\f3GL_TEXTURE_MAX_LOD\fP
-Sets the maximum level-of-detail parameter.  This floating-point value
-limits the selection of the lowest resolution mipmap (highest mipmap
-level). The initial value is 1000.
-.P
-.TP 10
-\%\f3GL_TEXTURE_BASE_LEVEL\fP
-Specifies the index of the lowest defined mipmap level. This is an
-integer value. The initial value is 0.
-.P
-.TP 10
-\%\f3GL_TEXTURE_MAX_LEVEL\fP
-Sets the index of the highest defined mipmap level. This is an integer
-value. The initial value is 1000.
-.P
-.TP 10
-\%\f3GL_TEXTURE_WRAP_S\fP
-Sets the wrap parameter for texture coordinate $s$ to either
-\%\f3GL_CLAMP\fP, \%\f3GL_CLAMP_TO_EDGE\fP, or \%\f3GL_REPEAT\fP.
-\%\f3GL_CLAMP\fP causes $s$ coordinates to be clamped to the range [0,1]
-and is useful for preventing wrapping artifacts when mapping
-a single image onto an object.
-\%\f3GL_CLAMP_TO_EDGE\fP causes $s$ coordinates to be clamped to the range
-$left [ {1 over 2N}, 1 - {1 over 2N} right ]$, where $N$ is the size
-of the texture in the direction of clamping.
-\%\f3GL_REPEAT\fP causes the integer part of the $s$ coordinate to be ignored;
-the GL uses only the fractional part,
-thereby creating a repeating pattern. 
-Border texture elements are accessed only if wrapping is set to \%\f3GL_CLAMP\fP.
-Initially, \%\f3GL_TEXTURE_WRAP_S\fP is set to \%\f3GL_REPEAT\fP.
-.P
-.TP 10
-\%\f3GL_TEXTURE_WRAP_T\fP
-Sets the wrap parameter for texture coordinate $t$ to either
-\%\f3GL_CLAMP\fP, \%\f3GL_CLAMP_TO_EDGE\fP, or \%\f3GL_REPEAT\fP.
-See the discussion under \%\f3GL_TEXTURE_WRAP_S\fP. 
-Initially, \%\f3GL_TEXTURE_WRAP_T\fP is set to \%\f3GL_REPEAT\fP.
-.TP 10
-\%\f3GL_TEXTURE_WRAP_R\fP
-Sets the wrap parameter for texture coordinate $r$ to either
-\%\f3GL_CLAMP\fP, \%\f3GL_CLAMP_TO_EDGE\fP, or \%\f3GL_REPEAT\fP.
-See the discussion under \%\f3GL_TEXTURE_WRAP_S\fP. 
-Initially, \%\f3GL_TEXTURE_WRAP_R\fP is set to \%\f3GL_REPEAT\fP.
-.TP
-\%\f3GL_TEXTURE_BORDER_COLOR\fP
-Sets a border color.
-\f2params\fP contains four values that comprise the RGBA color
-of the texture border. 
-Integer color components are interpreted linearly such that the most
-positive integer maps to 1.0,
-and the most negative integer maps to -1.0.
-The values are clamped to the range [0,1] when they are specified.
-Initially, the border color is (0, 0, 0, 0).
-.TP 10
-\%\f3GL_TEXTURE_PRIORITY\fP
-Specifies the texture residence priority of the currently bound texture.
-Permissible values are in the range [0,\ 1].
-See \%\f3glPrioritizeTextures\fP and \%\f3glBindTexture\fP for more information.
-.SH NOTES
-\%\f3GL_TEXTURE_3D\fP, \%\f3GL_TEXTURE_MIN_LOD\fP, \%\f3GL_TEXTURE_MAX_LOD\fP,
-\%\f3GL_TEXTURE_BASE_LEVEL\fP, and \%\f3GL_TEXTURE_MAX_LEVEL\fP are only
-available if the GL version is 1.2 or greater.
-.P
-Suppose that a program has enabled texturing
-(by calling \%\f3glEnable\fP
-with argument \%\f3GL_TEXTURE_1D\fP, \%\f3GL_TEXTURE_2D\fP, or \%\f3GL_TEXTURE_3D\fP)
-and has set \%\f3GL_TEXTURE_MIN_FILTER\fP to one of the functions
-that requires a mipmap.
-If either the dimensions of the texture images currently defined
-(with previous calls to \%\f3glTexImage1D\fP, \%\f3glTexImage2D\fP, 
-\%\f3glTexImage3D\fP,
-\%\f3glCopyTexImage1D\fP, or \%\f3glCopyTexImage2D\fP) 
-do not follow the proper sequence for mipmaps
-(described above),
-or there are fewer texture images defined than are needed,
-or the set of texture images have differing numbers of texture components,
-then it is as if texture mapping were disabled. 
-.P
-Linear filtering accesses the four nearest texture elements only in 2D
-textures.
-In 1D textures, linear filtering accesses the two nearest texture
-elements.
-.P
-When the \%\f3GL_ARB_multitexture\fP extension is supported, \%\f3glTexParameter\fP
-specifies the texture parameters for the active texture unit, specified
-by calling \%\f3glActiveTextureARB\fP.
-.SH ERRORS

-\f2size\fP
-Specifies the number of coordinates per vertex; must be 2, 3, or
-4. The initial value is 4.
-.TP
-\f2type\fP
-Specifies the data type of each coordinate in the array.
-Symbolic constants
-\%\f3GL_SHORT\fP,
-\%\f3GL_INT\fP,
-\%\f3GL_FLOAT\fP,
-and \%\f3GL_DOUBLE\fP 
-are accepted. The initial value is \%\f3GL_FLOAT\fP. 
-.TP
-\f2stride\fP 
-Specifies the byte offset between consecutive 
-vertices. If \f2stride\fP is 0, the vertices are understood to be tightly packed in 
-the array. The initial value
-is 0. 
-.TP
-\f2ptr\fP 
-Specifies a pointer to the first coordinate of the first vertex in the
-array. The initial value is 0.
-.SH DESCRIPTION
-\%\f3glVertexPointer\fP specifies the location and data  of an array of vertex coordinates
-to use when rendering.
-\f2size\fP specifies the number of coordinates per vertex and
-\f2type\fP the data type of
-the coordinates. \f2stride\fP specifies the byte stride from one
-vertex to the next allowing vertices and attributes
-to be packed into a single array or stored in separate arrays.
-(Single-array storage may be more efficient on some implementations;
-see \%\f3glInterleavedArrays\fP.)
-When a vertex array is
-specified, \f2size\fP, \f2type\fP, \f2stride\fP, and \f2ptr\fP are saved as client-side
-state.
-.P
-To enable and disable the vertex array, call \%\f3glEnableClientState\fP and
-.br 
-\%\f3glDisableClientState\fP with the argument \%\f3GL_VERTEX_ARRAY\fP. If
-enabled, the vertex array is used when 
-\%\f3glDrawArrays\fP, \%\f3glDrawElements\fP, or \%\f3glArrayElement\fP is called.
-.P
-Use \%\f3glDrawArrays\fP to construct a sequence of primitives (all of
-the same type)
-from prespecified vertex and vertex attribute arrays.
-Use \%\f3glArrayElement\fP to specify primitives
-by indexing vertices and vertex attributes  and \%\f3glDrawElements\fP to
-construct a sequence of primitives by indexing vertices and vertex attributes.
-.SH NOTES
-\%\f3glVertexPointer\fP is available only if the GL version is 1.1 or greater.
-.P
-The vertex array is initially disabled and isn't accessed when
-\%\f3glArrayElement\fP, \%\f3glDrawElements\fP or \%\f3glDrawArrays\fP is called.
-.P
-Execution of \%\f3glVertexPointer\fP is not allowed between the execution of
-\%\f3glBegin\fP and the corresponding execution of \%\f3glEnd\fP,
-but an error may or may not be generated. If no error is generated,
-the operation is undefined.
-.P
-\%\f3glVertexPointer\fP is typically implemented on the client side.
-.P
-Vertex array parameters are client-side state and are therefore not
-saved or restored by \%\f3glPushAttrib\fP and \%\f3glPopAttrib\fP.
-Use \%\f3glPushClientAttrib\fP and \%\f3glPopClientAttrib\fP instead.
-.SH ERRORS
-\%\f3GL_INVALID_VALUE\fP is generated if \f2size\fP is not 2, 3, or 4.

-Ignored if \f3GLX_RGBA\fP is asserted.
-.BP
-.TP
-\f3GLX_LEVEL\fP
-Must be followed by an integer buffer-level specification.
-This specification is honored exactly.
-Buffer level zero corresponds to the main frame buffer of the display.
-Buffer level one is the first overlay frame buffer, level two the second

-.SH DESCRIPTION
-\f3glXCopyContext\fP copies selected groups of state variables from \f2src\fP to \f2dst\fP.
-\f2mask\fP indicates which groups of state variables are to be copied.
-\f2mask\fP contains the bitwise OR of the same symbolic names that are

-If \f2direct\fP is \f3True\fP,

-If \f2direct\fP is \f3False\fP,

-not a visual ID or a pointer to a \f3Visual\fP.
-.TP
-\f2attrib\fP
-Specifies the visual attribute to be returned.
-.TP
-\f2value\fP
-Returns the requested value.
-.SH DESCRIPTION
-\f3glXGetConfig\fP sets \f2value\fP to the \f2attrib\fP value of windows or GLX pixmaps
-created with respect to \f2vis\fP.
-\f3glXGetConfig\fP returns an error code if it fails for any reason.
-Otherwise, zero is returned.
-.P
-\f2attrib\fP is one of the following:
-.P
-.TP 22
-\f3GLX_USE_GL\fP
-\f3True\fP if OpenGL rendering is supported by this visual,
-\f3False\fP otherwise.
-.TP
-\f3GLX_BUFFER_SIZE\fP
-Number of bits per color buffer.
-For RGBA visuals, \f3GLX_BUFFER_SIZE\fP is the sum of
-\f3GLX_RED_SIZE\fP,
-\f3GLX_GREEN_SIZE\fP,
-\f3GLX_BLUE_SIZE\fP, and
-\f3GLX_ALPHA_SIZE\fP.
-For color index visuals, \f3GLX_BUFFER_SIZE\fP is the size of the
-color indexes.
-.TP
-\f3GLX_LEVEL\fP
-Frame buffer level of the visual.
-Level zero is the default frame buffer.
-Positive levels correspond to frame buffers that overlay the default buffer,
-and negative levels correspond to frame buffers that underlay the default
-buffer.
-.TP
-\f3GLX_RGBA\fP
-\f3True\fP if color buffers store red, green, blue, and alpha values.
-\f3False\fP if they store color indexes.
-.TP
-\f3GLX_DOUBLEBUFFER\fP
-\f3True\fP if color buffers exist in front/back pairs that can be swapped,
-\f3False\fP otherwise.
-.TP
-\f3GLX_STEREO\fP
-\f3True\fP if color buffers exist in left/right pairs,
-\f3False\fP otherwise.
-.TP
-\f3GLX_AUX_BUFFERS\fP
-Number of auxiliary color buffers that are available.
-Zero indicates that no auxiliary color buffers exist.
-.TP
-\f3GLX_RED_SIZE\fP
-Number of bits of red stored in each color buffer.
-Undefined if \f3GLX_RGBA\fP is \f3False\fP.

-\f3GLX_ACCUM_BLUE_SIZE\fP
-Number of bits of blue stored in the accumulation buffer.
-.TP
-\f3GLX_ACCUM_ALPHA_SIZE\fP
-Number of bits of alpha stored in the accumulation buffer.
-.TE
-.P
-The X protocol allows a single visual ID to be instantiated with
-different numbers of bits per pixel.
-Windows or GLX pixmaps that will be rendered with OpenGL, however,
-must be instantiated with a color buffer depth of \f3GLX_BUFFER_SIZE\fP.
-.P
-Although a GLX implementation can export many visuals that support GL
-rendering,
-it must support 
-at least one RGBA visual. This visual must have at 
-least one color buffer,
-a stencil buffer of at least 1 bit,
-a depth buffer of at least 12 bits,
-and an accumulation buffer.
-Alpha bitplanes are optional in this visual.
-However,
-its color buffer size must be as great as that of the
-deepest \f3TrueColor\fP, \f3DirectColor\fP,
-\f3PseudoColor\fP, or \f3StaticColor\fP visual supported on level zero,
-and it must itself be made available on level zero.
-.P
-In addition, if the X server exports a \f3PseudoColor\fP 
-or \f3StaticColor\fP visual on framebuffer level 0, a color index 
-visual is also required on that level.
-It must have  
-at least one color buffer,
-a stencil buffer of at least 1 bit,
-and a depth buffer of at least 12 bits.
-This visual must 
-have as many 
-color bitplanes as the deepest
-\f3PseudoColor\fP or \f3StaticColor\fP visual supported on level 0.
-.P
-Applications are best written to select the visual that most closely
-meets their requirements.
-Creating windows or GLX pixmaps with unnecessary buffers can result in
-reduced rendering performance as well as poor resource allocation.
-.SH NOTES
-\f3XVisualInfo\fP is defined in \f2Xutil.h.\fP
-It is a structure that includes \f2visual\fP, \f2visualID\fP, \f2screen\fP, and
-\f2depth\fP elements.
-.SH ERRORS
-\f3GLX_NO_EXTENSION\fP is returned if \f2dpy\fP does not support the GLX

-.SH NAME
-glXIntro
-\- Introduction to OpenGL in the X window system
-
-.SH OVERVIEW
-OpenGL (called GL in other pages) is a high-performance 3D-oriented renderer.
-It is available in the X window system through the GLX extension.
-To determine whether the GLX extension is supported by an X server,
-and if so, what version is supported, call \f3glXQueryExtension\fP
-and \f3glXQueryVersion\fP.
-.P
-GLX extended servers make a subset of their visuals available
-for OpenGL rendering.
-Drawables created with these visuals can also be rendered using
-the core X renderer
-and with the renderer of any other X extension that is compatible
-with all core X visuals.
-.P
-GLX extends drawables with several buffers other than
-the standard color buffer.
-These buffers include back and auxiliary color buffers,
-a depth buffer,
-a stencil buffer,
-and a color accumulation buffer.
-Some or all are included in each X visual that supports OpenGL.
-.P
-To render using OpenGL into an X drawable,
-you must first choose a visual that defines the required OpenGL buffers.
-\f3glXChooseVisual\fP can be used to simplify selecting a compatible visual.
-If more control of the selection process is required,
-use \f3XGetVisualInfo\fP and \f3glXGetConfig\fP to select among
-all the available visuals.
-.P
-Use the selected visual to create both a GLX context and an X
-drawable.
-GLX contexts are created with \f3glXCreateContext\fP,
-and drawables are created with either \f3XCreateWindow\fP or
-\f3glXCreateGLXPixmap\fP.
-Finally,
-bind the context and the drawable together using \f3glXMakeCurrent\fP.
-This context/drawable pair becomes the current context and current
-drawable,
-and it is used by all OpenGL commands until \f3glXMakeCurrent\fP is
-called with different arguments.
-.P
-Both core X and OpenGL commands can be used to operate on the
-current drawable.
-The X and OpenGL command streams are not synchronized,
-however,
-except at explicitly created boundaries generated by calling
-\f3glXWaitGL\fP, \f3glXWaitX\fP, \f3XSync\fP, and \f3glFlush\fP.
-.SH EXAMPLES
-Below is the minimum code required to create an RGBA-format,
-X window that's compatible with OpenGL and to clear it to yellow.
-The code is correct,
-but it does not include any error checking.
-Return values \f2dpy\fP,
-\f2vi\fP,
-\f2cx\fP,
-\f2cmap\fP, and
-\f2win\fP should all be tested.

-.SH NOTES
-A color map must be created and passed to \f3XCreateWindow\fP.
-See the preceding example code.
-.P
-A GLX context must be created and attached to an X drawable before
-OpenGL commands can be executed.
-OpenGL commands issued while no context/drawable pair is current
-result in undefined behavior.
-.P
-Exposure events indicate that \f2all\fP buffers associated with the
-specified window may be damaged and should be repainted.
-Although certain buffers of some visuals on some systems
-may never require repainting
-(the depth buffer, for example),
-it is incorrect to write a program assuming that these buffers will
-not be damaged.
-.P
-GLX commands manipulate XVisualInfo structures rather than pointers to
-visuals or visual IDs.
-XVisualInfo structures contain \f2visual\fP,
-\f2visualID\fP,
-\f2screen\fP, and
-\f2depth\fP elements,
-as well as other X-specific information.
-.SH USING GLX EXTENSIONS
-All supported GLX extensions will have a corresponding definition in glx.h
-and a token in the extension string returned by \f3glXQueryExtensionsString\fP.
-For example, if the \f3EXT_visual_info\fP extension is supported,
-then this token will be defined in glx.h and \f3EXT_visual_info\fP
-will appear in the extension 
-string returned by \f3glXQueryExtensionsString\fP. The definitions in glx.h
-can be used at compile time to determine if procedure calls corresponding
-to an extension exist in the library. 
-.P
-OpenGL itself has also been extended. Refer to \f3glIntro\fP for more
-information.
-.P
-.SH GLX 1.1 and GLX 1.2
-GLX 1.2 is now supported. It is backward compatible with GLX 1.1 and
-GLX 1.0.
-.P
-GLX 1.2 corresponds to OpenGL version 1.1 and introduces the following
-new call: \f3glGetCurrentDisplay\fP.
-.P
-GLX 1.1 corresponds to OpenGL version 1.0 and introduces the
-following new calls:
-\f3glXQueryExtensionsString\fP, \f3glXQueryServerString\fP, and
-\f3glXGetClientString\fP.
-.P
-Call \f3glQueryVersion\fP
-to determine at runtime what version of GLX is available. \f3glQueryVersion\fP
-returns the version that is supported on the connection. Thus
-if 1.2 is returned, both the client and server support GLX 1.2.
-You can also check the GLX version at compile time: GLX_VERSION_1_1
-will be defined in glx.h if GLX 1.1 calls are supported and
-GLX_VERSION_1_2 will be defined if GLX 1.2 calls are supported.

-.TP
-\f2ctx\fP
-Specifies a GLX rendering context that is to be attached to \f2drawable\fP.
-.SH DESCRIPTION
-\f3glXMakeCurrent\fP does two things:
-It makes \f2ctx\fP the current GLX rendering context of the calling thread,
-replacing the previously current context if there was one,
-and it attaches \f2ctx\fP to a GLX drawable,
-either a window or a GLX pixmap.
-As a result of these two actions,
-subsequent GL rendering calls
-use rendering context \f2ctx\fP to modify GLX drawable \f2drawable\fP.
-Because \f3glXMakeCurrent\fP always replaces the current rendering context with \f2ctx\fP,
-there can be only one current context per thread.
-.P
-Pending commands to the
-previous context, if any, are flushed before it is released.
-.P
-The first time \f2ctx\fP is made current to any thread,
-its viewport is set to the full size of \f2drawable\fP.
-Subsequent calls by any thread to \f3glXMakeCurrent\fP with \f2ctx\fP
-have no effect on its viewport.
-.P
-To release the current context without assigning a new one,
-call \f3glXMakeCurrent\fP with \f2drawable\fP set \f3None\fP and \f2ctx\fP
-set to \f3NULL\fP
-.P
-\f3glXMakeCurrent\fP returns \f3True\fP if it is successful,
-\f3False\fP otherwise.
-If \f3False\fP is returned, the previously current rendering context
-and drawable (if any) remain unchanged.
-.SH NOTES
-A \f2process\fP is a single-execution environment,
-implemented in a single address space,
-consisting of one or more threads.
-.P
-A \f2thread\fP is one of a set of subprocesses that share
-a single address space,
-but maintain separate program counters,
-stack spaces,
-and other related global data.
-A \f2thread\fP that is the only member of its subprocess group
-is equivalent to a \f2process\fP.
-.SH ERRORS

-\f3GLXBadContextState\fP is also generated if the rendering context current
-to the calling thread has GL renderer state \f3GL_FEEDBACK\fP or
-\f3GL_SELECT\fP.
-.P
-\f3GLXBadCurrentWindow\fP is generated if there are pending GL

-\f3glXSwapBuffers\fP promotes the contents of the back buffer of \f2drawable\fP to become

-The update typically takes place during the vertical retrace of

-\f3glXSwapBuffers\fP performs an implicit \f3glFlush\fP before it returns.
-Subsequent OpenGL commands may be issued immediately after calling \f3glXSwapBuffers\fP,
-but are not executed until the buffer exchange is completed.
-.P
-If \f2drawable\fP was not created with respect to a double-buffered visual,
-\f3glXSwapBuffers\fP has no effect,
-and no error is generated.
-.SH NOTES
-The contents of the back buffer become undefined after
-a swap. Note that this applies to pbuffers as well as windows.
-.P
-All GLX rendering contexts share the same notion of which are front buffers
-and which are back buffers.
-One consequence is that when multiple clients are rendering to the same
-double-buffered window,
-all of them should finish rendering before one of them issues the command
-to swap buffers.
-The clients are responsible for implementing this synchronization.
-Typically this is accomplished by executing \f3glFinish\fP and then
-using a semaphore in shared memory to rendezvous before swapping.

-.P
-\f3GLXBadCurrentWindow\fP is generated if \f2dpy\fP and \f2drawable\fP are

-Although the same result can be achieved using \f3XSync\fP,
-\f3glXWaitX\fP does not require a round trip to the server,
-and it is therefore more efficient in cases where client and server
-are on separate machines.
-.P
-\f3glXWaitX\fP is ignored if there is no current GLX context.
-.SH NOTES
-\f3glXWaitX\fP may or may not flush the GL stream.
-.SH ERRORS
-\f3GLXBadCurrentWindow\fP is generated if the drawable associated
-with the current context of the calling thread is a window, and that
-window is no longer valid.

-.SH DESCRIPTION
-Use \%\f3gluBeginTrim\fP to mark the beginning of a
-trimming loop, and \%\f3gluEndTrim\fP to mark the end 
-of a trimming loop. A trimming loop is 
-a set of oriented curve segments (forming a closed curve) that
-define boundaries of a NURBS surface. You include these
-trimming loops in the definition of a NURBS 
-surface, between calls to \%\f3gluBeginSurface\fP and \%\f3gluEndSurface\fP.
-.P
-The definition for a NURBS surface can contain many
-trimming loops. For example, if you wrote a definition
-for a NURBS surface that resembled a rectangle with
-a hole punched out, the definition would contain two 
-trimming loops. One loop would define the outer edge
-of the rectangle; the other would define
-the hole punched out of the rectangle. The definitions
-of each of these trimming loops would be bracketed by a
-\%\f3gluBeginTrim\fP/\%\f3gluEndTrim\fP pair.
-.P
-The definition of a single closed trimming loop can consist
-of multiple curve segments, each described as a piecewise
-linear curve (see \%\f3gluPwlCurve\fP) or as a single NURBS
-curve (see \%\f3gluNurbsCurve\fP), or as a combination of 
-both in any order. The only library calls that can 
-appear in a trimming loop definition (between the calls
-to \%\f3gluBeginTrim\fP and \%\f3gluEndTrim\fP) are 
-\%\f3gluPwlCurve\fP and \%\f3gluNurbsCurve\fP.
-.P
-The area of the NURBS surface that is displayed is the
-region in the domain to the left of the trimming curve
-as the curve parameter increases. Thus, the retained
-region of the NURBS surface is inside a 
-counterclockwise trimming loop and outside a clockwise
-trimming loop. For the rectangle mentioned earlier,
-the trimming loop for the outer edge of the rectangle runs
-counterclockwise, while the trimming loop for the punched-out hole 
-runs clockwise.
-.P
-If you use more than one curve to define a single trimming 
-loop, the curve segments must form a closed loop (that is,
-the endpoint of each curve must be the starting point of the
-next curve, and the endpoint of the final curve must
-be the starting point of the first curve). If the 
-endpoints of the curve are sufficiently close together
-but not exactly coincident, they will be coerced to match.
-If the endpoints are not sufficiently close, an error results
-(see \%\f3gluNurbsCallback\fP).
-.P
-If a trimming loop definition contains multiple curves,
-the direction of the curves must be consistent (that is, the
-inside must be to the left of all of the curves). Nested
-trimming loops are legal as long as the curve orientations
-alternate correctly.
-If trimming curves are self-intersecting,
-or intersect one another, an error results.
-.P
-If no trimming information is given
-for a NURBS surface, the entire surface is drawn.
-.SH EXAMPLE
-This code fragment defines a trimming loop that consists of one
-piecewise linear curve, and two NURBS curves:

-.SH DESCRIPTION
-\%\f3gluBuild1DMipmapLevels\fP builds a subset of prefiltered one-dimensional texture maps of decreasing
-resolutions called a mipmap. This is used for the antialiasing of
-texture mapped primitives.
-.P
-A return value of zero indicates success, otherwise a GLU error code is
-returned (see \%\f3gluErrorString\fP).
-.P
-A series of mipmap levels from \f2base\fP to \f2max\fP is built by decimating 
-\f2data\fP in half 
-until size $1 ~times~ 1$ is reached. At each level, each texel in the
-halved mipmap level is an average of the corresponding two texels in the larger
-mipmap level. 
-\f3glTexImage1D\fP is called to load these mipmap levels from \f2base\fP
-to \f2max\fP. If \f2max\fP is larger than the highest mipmap level for the
-texture of the specified size, then a GLU error code is returned (see
-\%\f3gluErrorString\fP) and nothing is loaded.
-.P
-For example, if \f2level\fP is 2 and \f2width\fP is 16, the
-following levels are possible: $16 ~times~ 1$, $8 ~times~ 1$, $4 ~times~ 1$,
-$2 ~times~ 1$, $1 ~times~ 1$. These correspond
-to levels 2 through 6 respectively.
-If \f2base\fP is 3 and \f2max\fP is 5, then only mipmap levels $8 ~times~ 1$,
-$4 ~times~ 1$ and $2 ~times~ 1$ are
-loaded. However, if \f2max\fP is 7 then an error is returned and nothing is
-loaded since \f2max\fP is larger than the highest mipmap level which is, in 
-this case, 6.
-.P
-The highest mipmap level can be derived from the formula
-${log sub 2} (\f2width\fP^{2 sup \f2level\fP})$.
-.P
-See the \f3glTexImage1D\fP reference page for a description of the
-acceptable values for \f2type\fP parameter. See the \f3glDrawPixels\fP 
-reference page for a description of the acceptable values 
-for \f2level\fP parameter.

-.SH DESCRIPTION
-\%\f3gluBuild1DMipmaps\fP builds a series of prefiltered one-dimensional texture maps of decreasing
-resolutions called a mipmap. This is used for the antialiasing of
-texture mapped primitives.
-.P
-A return value of zero indicates success, otherwise a GLU error code is
-returned (see \%\f3gluErrorString\fP).
-.P
-Initially, the \f2width\fP of \f2data\fP is checked to see if it is
-a power of 2. If not, a copy of \f2data\fP is scaled up or down to the
-nearest power of 2. (If \f2width\fP is exactly between powers of 2, then
-the copy of \f2data\fP will scale upwards.)  This copy will be used for
-subsequent mipmapping operations described below. 
-For example, if \f2width\fP is 57 then a copy of \f2data\fP
-will scale up to 64 before mipmapping
-takes place.
-.P
-Then, proxy textures (see \f3glTexImage1D\fP) are used to determine if
-the implementation can fit the requested texture. If not, \f2width\fP is
-continually halved until it fits.
-.P
-Next, a series of mipmap levels is built by decimating a copy of
-\f2data\fP in half
-until size $1 ~times~ 1$ is reached. At each level, each texel in the
-halved mipmap level is an average of the corresponding two texels in the larger
-mipmap level.
-.P
-\f3glTexImage1D\fP is called to load each of these mipmap levels.
-Level 0 is a copy of \f2data\fP. 
-The highest level is ${log sub 2}(\f2width\fP)$.
-For example, if \f2width\fP is 64 and the implementation can store a texture of
-this size, the following mipmap levels are
-built: $64 ~times~ 1$, $32 ~times~ 1$, $16 ~times~ 1$, $8 ~times~ 1$,
-$4 ~times~ 1$, $2 ~times~ 1$ and $1 ~times~ 1$. These correspond to 
-levels 0 through 6, respectively.
-.P
-See the \f3glTexImage1D\fP reference page for a description of the
-acceptable values for the \f2type\fP parameter. See the \f3glDrawPixels\fP 
-reference page for a description of the acceptable values 
-for the \f2data\fP parameter.
-.SH NOTES
-Note that there is no direct way of querying the maximum level. This can
-be derived indirectly via \f3glGetTexLevelParameter\fP. First, query
-for the
-width actually used at level 0. 
-(The width may not be equal to \f2width\fP since
-proxy textures might have scaled it to fit the implementation.)
-Then the maximum
-level can be derived from the formula ${log sub 2}(\f2width\fP)$.

-.SH DESCRIPTION
-\%\f3gluBuild2DMipmapLevels\fP builds a subset of prefiltered two-dimensional texture maps of decreasing
-resolutions called a mipmap. This is used for the antialiasing of
-texture mapped primitives.
-.P
-A return value of zero indicates success, otherwise a GLU error code is
-returned (see \%\f3gluErrorString\fP).
-.P
-A series of mipmap levels from \f2base\fP to \f2max\fP is built by decimating 
-\f2data\fP in half along
-both dimensions until size $1 ~times~ 1$ is reached. At each level, each texel in the
-halved mipmap level is an average of the corresponding four texels in the larger
-mipmap level. (In the case of rectangular images, the decimation will ultimately 
-reach an $N ~times~ 1$ or $1 ~times~ N$ configuration. Here, two texels are
-averaged instead.)
-\f3glTexImage2D\fP is called to load these mipmap levels from \f2base\fP
-to \f2max\fP. If \f2max\fP is larger than the highest mipmap level for the
-texture of the specified size, then a GLU error code is returned (see
-\%\f3gluErrorString\fP) and nothing is loaded.
-.P
-For example, if \f2level\fP is 2 and \f2width\fP is 16 and \f2height\fP is 8, the
-following levels are possible: $16 ~times~ 8$, $8 ~times~ 4$, $4 ~times~ 2$,
-$2 ~times~ 1$, $1 ~times~ 1$. These correspond to levels 2 through 6
-respectively.  If \f2base\fP is 3 and \f2max\fP is 5, then only mipmap levels
-$8 ~times~ 4$, $4 ~times~ 2$ and $2 ~times~ 1$ are loaded. However, if \f2max\fP
-is 7 then an error is returned and nothing is loaded since \f2max\fP is
-larger than the highest mipmap level which is, in this case, 6.
-.P
-The highest mipmap level can be derived from the formula
-log2(max(\f2width\fP,\f2height\fP)*(2^\f2level\fP)).
-.P
-See the \f3glTexImage1D\fP reference page for a description of the
-acceptable values for \f2format\fP parameter. See the \f3glDrawPixels\fP 
-reference page for a description of the acceptable values 
-for \f2type\fP parameter.

-.SH DESCRIPTION
-\%\f3gluBuild2DMipmaps\fP builds a series of prefiltered two-dimensional texture maps of decreasing
-resolutions called a mipmap. This is used for the antialiasing of
-texture-mapped primitives.
-.P
-A return value of zero indicates success, otherwise a GLU error code is
-returned (see \%\f3gluErrorString\fP).
-.P
-Initially, the \f2width\fP and \f2height\fP of \f2data\fP are checked to see if they
-are a power of 2. If not, a copy of \f2data\fP (not \f2data\fP), is scaled up
-or down to the nearest power of 2. This copy will be used for subsequent
-mipmapping operations described below. (If \f2width\fP or \f2height\fP is exactly
-between powers of 2, then the copy of \f2data\fP will scale upwards.)  For
-example, if \f2width\fP is 57 and \f2height\fP is 23 then a copy of \f2data\fP will
-scale up to 64 in \f2width\fP and down to 16 in depth, before mipmapping takes
-place.
-.P
-Then, proxy textures (see \f3glTexImage2D\fP) are used to determine if
-the implementation can fit the requested texture. If not, both dimensions
-are continually halved until it fits. (If the OpenGL version is \(<= 1.0,
-both maximum texture dimensions are clamped to the value returned
-by \f3glGetIntegerv\fP with the argument \%\f3GL_MAX_TEXTURE_SIZE\fP.)
-.P
-Next, a series of mipmap levels is built by decimating a copy of \f2data\fP
-in half along both dimensions until size $1 ~times~ 1$ is reached. At
-each level,
-each texel in the halved mipmap level is an average of the corresponding
-four texels in the larger mipmap level. (In the case of rectangular
-images, the decimation will ultimately reach an $N ~times~ 1$ or
-$1 ~times~ N$ configuration. Here, two texels are averaged instead.)
-.P
-\f3glTexImage2D\fP is called to load each of these mipmap levels.
-Level 0 is a copy of \f2data\fP.  The highest level is
-${log sub 2} ( max ("width","height"))$.  For example,
-if \f2width\fP is 64 and \f2height\fP is 16
-and the implementation can store a texture of this size, the following
-mipmap levels are built: $64 ~times~ 16$, $32 ~times~ 8$, $16 ~times~ 4$,
-$8 ~times~ 2$, $4 ~times~ 1$, $2 ~times~ 1$ and $1 ~times~ 1$. These correspond to
-levels 0 through 6, respectively.
-.P
-See the \f3glTexImage1D\fP reference page for a description of the
-acceptable values for \f2format\fP parameter. See the \f3glDrawPixels\fP 
-reference page for a description of the acceptable values 
-for \f2type\fP parameter.
-.SH NOTES
-
-Note that there is no direct way of querying the maximum level. This can
-be derived indirectly via \f3glGetTexLevelParameter\fP. First, query
-for the width and height actually used at level 0.  (The width and
-height may not be equal to \f2width\fP and \f2height\fP respectively since proxy
-textures might have scaled them to fit the implementation.)  Then the
-maximum level can be derived from the formula
-${log sub 2}( max (\f2width\fP,\f2height\fP))$.

-.SH DESCRIPTION
-\%\f3gluBuild3DMipmapLevels\fP builds a subset of prefiltered three-dimensional texture maps of
-decreasing resolutions called a mipmap. This is used for the antialiasing of
-texture mapped primitives.
-.P
-A return value of zero indicates success, otherwise a GLU error code is
-returned (see \%\f3gluErrorString\fP).
-.P
-A series of mipmap levels from \f2base\fP to \f2max\fP is built by
-decimating \f2data\fP in half along both dimensions until size $1 ~times~ 1
-~times~ 1$ is reached. At each level, each texel in the halved mipmap
-level is an average of the corresponding eight texels in the larger
-mipmap level. (If exactly one of the dimensions is 1, four texels are
-averaged.  If exactly two of the dimensions are 1, two texels are
-averaged.)  \f3glTexImage3D\fP is called to load these mipmap levels
-from \f2base\fP to \f2max\fP. If \f2max\fP is larger than the highest mipmap
-level for the texture of the specified size, then a GLU error code is
-returned (see \%\f3gluErrorString\fP) and nothing is loaded.
-.P
-For example, if \f2level\fP is 2 and \f2width\fP is 16, \f2height\fP is 8 and \f2depth\fP
-is 4, the following levels are possible: $16 ~times~ 8 ~times~ 4$, $8 ~times~
-4 ~times~ 2$, $4 ~times~ 2 ~times~ 1$, $2 ~times~ 1 ~times~ 1$,
-$1 ~times~ 1 ~times~ 1$.
-These correspond to levels 2 through 6 respectively.  If \f2base\fP is
-3 and \f2max\fP is 5, then only mipmap levels $8 ~times~ 4 ~times~ 2$, $4
-~times~ 2 ~times~ 1$ and $2 ~times~ 1 ~times~ 1$ are loaded. However, if
-\f2max\fP is 7 then an error is returned and nothing is loaded, since
-\f2max\fP is larger than the highest mipmap level which is, in this case,
-6.
-.P
-The highest mipmap level can be derived from the formula
-${log sub 2} ( max ("width","height","depth")^{2 sup "level"})$.
-.P
-See the \f3glTexImage1D\fP reference page for a description of the
-acceptable values for \f2format\fP parameter. See the \f3glDrawPixels\fP 
-reference page for a description of the acceptable values 
-for \f2type\fP parameter.

-.SH DESCRIPTION
-\%\f3gluBuild3DMipmaps\fP builds a series of prefiltered three-dimensional texture maps of
-decreasing resolutions called a mipmap. This is used for the antialiasing of
-texture-mapped primitives.
-.P
-A return value of zero indicates success, otherwise a GLU error code is
-returned (see \%\f3gluErrorString\fP).
-.P
-Initially, the \f2width\fP, \f2height\fP and \f2depth\fP of \f2data\fP are checked to
-see if they are a power of 2. If not, a copy of \f2data\fP (not \f2data\fP),
-is scaled up or down to the nearest power of 2. (If \f2width\fP, \f2height\fP or
-\f2depth\fP is exactly between powers of 2, then the copy of \f2data\fP will
-scale upwards.) This copy will be used for subsequent mipmapping
-operations described below.  For example, if \f2width\fP is 57, \f2height\fP is
-23 and \f2depth\fP is 24 then a copy of \f2data\fP will scale up to 64 in
-width, down to 16 in height and up to 32 in depth, before mipmapping
-takes place.
-.P
-Then, proxy textures (see \f3glTexImage3D\fP) are used to determine if
-the implementation can fit the requested texture. If not, all three dimensions
-are continually halved until it fits. 
-.P
-Next, a series of mipmap levels is built by decimating a copy of \f2data\fP
-in half along all three dimensions until size $1 ~times~ 1 ~times~ 1$ is
-reached. At each level, each texel in the halved mipmap level is an
-average of the corresponding eight texels in the larger mipmap
-level. (If exactly one of the dimensions is 1, four texels are averaged.
-If exactly two of the dimensions are 1, two texels are averaged.)
-.P
-\f3glTexImage3D\fP is called to load each of these mipmap levels.
-Level 0 is a copy of \f2data\fP.  The highest level is
-${log sub 2} ( max ("width","height","depth"))$.
-For example, if \f2width\fP is 64, \f2height\fP is
-16 and \f2depth\fP is 32, and the implementation can store a texture of this
-size, the following mipmap levels are built: $64 ~times~ 16 ~times~ 32$,
-$32 ~times~ 8 ~times~ 16$, $16 ~times~ 4 ~times~ 8$,
-$8 ~times~ 2 ~times~ 4$, $4 ~times~ 1 ~times~ 2$,
-$2 ~times~ 1 ~times~ 1$
-and $1 ~times~ 1 ~times~ 1$. These correspond
-to levels 0 through 6, respectively.
-.P
-See the \f3glTexImage1D\fP reference page for a description of the
-acceptable values for \f2format\fP parameter. See the \f3glDrawPixels\fP 
-reference page for a description of the acceptable values 
-for \f2type\fP parameter.
-.SH NOTES
-Note that there is no direct way of querying the maximum level. This can
-be derived indirectly via \f3glGetTexLevelParameter\fP. First, query
-for the width, height and depth actually used at level 0.  (The width,
-height and depth may not be equal to \f2width\fP, \f2height\fP and \f2depth\fP
-respectively since proxy textures might have scaled them to fit the
-implementation.)  Then the maximum level can be derived from the formula
-${log sub 2} ( max ("width","height","depth"))$.

-The sampling matrix determines how finely a NURBS curve or surface

-The culling matrix is used in deciding if a NURBS curve or surface

-.P
-\%\f3gluLoadSamplingMatrices\fP is necessary only if the \%\f3GLU_AUTO_LOAD_MATRIX\fP property is turned

-Although it can be convenient to leave the \%\f3GLU_AUTO_LOAD_MATRIX\fP
-property turned on, there can be a performance penalty for doing so.
-(A round trip to the GL server is needed to fetch the current values

-\%\f3gluLookAt\fP creates a viewing matrix derived from an eye point, a reference

-When a typical projection matrix is used,
-the center of the scene therefore maps to the center of the viewport.

-vector projected onto the viewing plane is mapped to the positive \f2y\fP 
-axis so that it points upward in the viewport.
-The \f2UP\fP vector must not be parallel to the line of sight from the
-eye point to the reference point.

-\%\f3GLU_INTERIOR\fP,
-\%\f3GLU_UNKNOWN\fP,
-\%\f3GLU_CCW\fP, and
-\%\f3GLU_CW\fP.
-.SH DESCRIPTION
-\%\f3gluNextContour\fP is used in describing polygons with multiple contours. After the first
-contour has been described through a series of \%\f3gluTessVertex\fP calls, 
-a \%\f3gluNextContour\fP call indicates that the previous contour is complete and that the
-next contour is about to begin.
-Another series of \%\f3gluTessVertex\fP calls is then used to describe the new 
-contour. This process can be repeated until all contours have been described.
-.P
-\f2type\fP defines what type of contour follows.
-The legal contour types are as follows:
-.TP 18
-\%\f3GLU_EXTERIOR\fP
-An exterior contour defines an exterior boundary of the polygon.
-.TP
-\%\f3GLU_INTERIOR\fP
-An interior contour defines an interior boundary of the polygon (such as 
-a hole).
-.TP
-\%\f3GLU_UNKNOWN\fP
-An unknown contour is analyzed by the library to determine if it is interior
-or exterior.
-.TP
-\%\f3GLU_CCW\fP, 
-.TP
-\%\f3GLU_CW\fP
-The first \%\f3GLU_CCW\fP or \%\f3GLU_CW\fP contour defined is considered to 
-be exterior. All other contours are considered to be exterior if they 
-are oriented in the same direction (clockwise or counterclockwise) as 
-the first contour, and interior if they are not.
-.P
-If one contour is of type \%\f3GLU_CCW\fP or \%\f3GLU_CW\fP, then all 
-contours must be of the same type (if they are not, then all \%\f3GLU_CCW\fP
-and \%\f3GLU_CW\fP contours will be changed to \%\f3GLU_UNKNOWN\fP).
-.P
-Note that there is no real difference between the \%\f3GLU_CCW\fP and 
-\%\f3GLU_CW\fP contour types.
-.P
-Before the first contour is described, \%\f3gluNextContour\fP can be called to 
-define the type of the first contour.
-If \%\f3gluNextContour\fP is not called before the first contour, then the first contour is 
-marked \%\f3GLU_EXTERIOR\fP.
-.P
-This command is obsolete and is provided for backward compatibility
-only. Calls to \%\f3gluNextContour\fP are mapped to \%\f3gluTessEndContour\fP
-followed by 
-\%\f3gluTessBeginContour\fP.
-.SH EXAMPLE
-A quadrilateral with a triangular hole in it can be described as follows:
-.sp
-.Ex
-gluBeginPolygon(tobj);
-   gluTessVertex(tobj, v1, v1);
-   gluTessVertex(tobj, v2, v2);

-\%\f3gluNurbsCallback\fP is used to define a callback to be used by a NURBS

-\f2CallBackFunc\fP is NULL, then this callback will not get
-invoked and the related data, if any, will be lost.

-Except the error callback, these callbacks are used by NURBS tessellator (when \%\f3GLU_NURBS_MODE\fP is set to be \%\f3GLU_NURBS_TESSELLATOR\fP) to return back the OpenGL
-polygon primitives resulting from the tessellation. Note that there are two
-versions of each callback: one with a user data pointer and one without. If both versions for a particular callback are specified then the callback with 
-the user data pointer will be used. Note that ``userData'' is a copy of the pointer that was specified at the last call to \%\f3gluNurbsCallbackData\fP.
-.P
-The error callback function is effective no matter which value that
-\%\f3GLU_NURBS_MODE\fP is set to.
-All other callback functions are effective only when \%\f3GLU_NURBS_MODE\fP
-is set to \%\f3GLU_NURBS_TESSELLATOR\fP.

-\%\f3GLU_NURBS_TESSELLATOR\fP.
-.SH DESCRIPTION
-\%\f3gluNurbsProperty\fP is used to control properties stored in a NURBS object. These
-properties affect the way that a NURBS curve is rendered. The accepted 
-values for \f2property\fP are as follows:
-.TP 15
-\%\f3GLU_NURBS_MODE\fP
-\f2value\fP should be set to be either \%\f3GLU_NURBS_RENDERER\fP or
-\%\f3GLU_NURBS_TESSELLATOR\fP. When set to \%\f3GLU_NURBS_RENDERER\fP, NURBS objects
-are tessellated into OpenGL primitives and sent to the pipeline for
-rendering. When set to \%\f3GLU_NURBS_TESSELLATOR\fP, NURBS objects are
-tessellated into OpenGL primitives but the vertices, normals, colors, and/or textures are 
-retrieved back through a callback interface (see \%\f3gluNurbsCallback\fP). This allows the user to cache the
-tessellated results for further processing.
-The initial value is \%\f3GLU_NURBS_RENDERER\fP.
-.TP
-\%\f3GLU_SAMPLING_METHOD\fP 
-Specifies how a NURBS surface should be
-tessellated.
-\f2value\fP may be one of \%\f3GLU_PATH_LENGTH\fP,
-\%\f3GLU_PARAMETRIC_ERROR\fP,  \%\f3GLU_DOMAIN_DISTANCE\fP,
-\%\f3GLU_OBJECT_PATH_LENGTH\fP, or
-\%\f3GLU_OBJECT_PARAMETRIC_ERROR\fP.
-When set to \%\f3GLU_PATH_LENGTH\fP, the surface is rendered so that
-the maximum length, in 
-pixels, of the edges of the tessellation polygons is no greater than
-what is specified by \%\f3GLU_SAMPLING_TOLERANCE\fP. 
-.IP
-\%\f3GLU_PARAMETRIC_ERROR\fP specifies that the surface is rendered in such a 
-way that the value specified by \%\f3GLU_PARAMETRIC_TOLERANCE\fP describes the 
-maximum distance, in pixels, between the tessellation polygons and the
-surfaces they approximate. 
-.IP
-\%\f3GLU_DOMAIN_DISTANCE\fP allows users to specify, in parametric coordinates,
-how many sample points per unit length are taken in \f2u\fP, \f2v\fP
-direction.
-.IP
-\%\f3GLU_OBJECT_PATH_LENGTH\fP  is similar to \%\f3GLU_PATH_LENGTH\fP
-except that it is view independent, that is, the surface is rendered so that the maximum length, in object space, of edges of the tessellation polygons is no greater than what is specified by \%\f3GLU_SAMPLING_TOLERANCE\fP.
-.IP   
-\%\f3GLU_OBJECT_PARAMETRIC_ERROR\fP is similar to  \%\f3GLU_PARAMETRIC_ERROR\fP except that it is view independent, that is, the surface is rendered in such a way that the value specified by \%\f3GLU_PARAMETRIC_TOLERANCE\fP describes the maximum distance, in object space, between the tessellation polygons and the surfaces they approximate.
-.IP
-The initial value of \%\f3GLU_SAMPLING_METHOD\fP is \%\f3GLU_PATH_LENGTH\fP.
-.TP
-\%\f3GLU_SAMPLING_TOLERANCE\fP
-Specifies the maximum length, in pixels or in object space length unit,
-to use when the sampling method is set to \%\f3GLU_PATH_LENGTH\fP or
-\%\f3GLU_OBJECT_PATH_LENGTH\fP.
-The NURBS code is conservative when rendering a curve
-or surface, so the actual length can be somewhat shorter. The initial
-value is 50.0 pixels. 
-.TP
-\%\f3GLU_PARAMETRIC_TOLERANCE\fP
-Specifies the maximum distance, in pixels or in object space length unit,
-to use when the sampling method is \%\f3GLU_PARAMETRIC_ERROR\fP or
-\%\f3GLU_OBJECT_PARAMETRIC_ERROR\fP.
-The initial value is 0.5.
-.TP
-\%\f3GLU_U_STEP\fP
-Specifies the number of sample points per unit length taken
-along the \f2u\fP axis in parametric coordinates. It is needed when
-\%\f3GLU_SAMPLING_METHOD\fP is set to \%\f3GLU_DOMAIN_DISTANCE\fP.
-The initial value is 100.
-.TP
-\%\f3GLU_V_STEP\fP
-Specifies the number of sample points per unit length taken
-along the \f2v\fP axis in parametric coordinate. It is needed when
-\%\f3GLU_SAMPLING_METHOD\fP is set to \%\f3GLU_DOMAIN_DISTANCE\fP. The initial 
-value is 100.
-.TP
-\%\f3GLU_DISPLAY_MODE\fP
-\f2value\fP can be set to
-\%\f3GLU_OUTLINE_POLYGON\fP, \%\f3GLU_FILL\fP, or 
-\%\f3GLU_OUTLINE_PATCH\fP.
-When \%\f3GLU_NURBS_MODE\fP is set to be \%\f3GLU_NURBS_RENDERER\fP,
-\f2value\fP defines how a NURBS surface should be rendered.
-When \f2value\fP is set to \%\f3GLU_FILL\fP, the surface is rendered as a
-set of polygons. When \f2value\fP is set to
-\%\f3GLU_OUTLINE_POLYGON\fP, the NURBS library draws only the outlines
-of the polygons created by tessellation. When \f2value\fP is set to
-\%\f3GLU_OUTLINE_PATCH\fP just the outlines of patches and trim 
-curves defined by the user are drawn.
-.IP
-When \%\f3GLU_NURBS_MODE\fP is set to be \%\f3GLU_NURBS_TESSELLATOR\fP,
-\f2value\fP defines how a NURBS surface should be tessellated.
-When \%\f3GLU_DISPLAY_MODE\fP is set to \%\f3GLU_FILL\fP or
-\%\f3GLU_OUTLINE_POLYGON\fP, 
-the NURBS surface is tessellated into OpenGL triangle primitives which can be
-retrieved back  through callback functions. If \%\f3GLU_DISPLAY_MODE\fP is set to 
-\%\f3GLU_OUTLINE_PATCH\fP, only the outlines of the patches and trim curves are generated as a sequence of line strips which can be retrieved back through callback functions.
-.IP
-The initial value is \%\f3GLU_FILL\fP.
-.TP
-\%\f3GLU_CULLING\fP
-\f2value\fP is a boolean value that, when set to \%\f3GL_TRUE\fP, indicates that 
-a NURBS curve should be discarded prior to tessellation if its control points
-lie outside the current viewport. The initial value is \%\f3GL_FALSE\fP.
-.TP
-\%\f3GLU_AUTO_LOAD_MATRIX\fP
-\f2value\fP is a boolean value. When set to \%\f3GL_TRUE\fP, the NURBS code 
-downloads the projection matrix, the modelview matrix, and the 
-viewport from the GL server to compute sampling and 
-culling
-matrices for each NURBS curve that is rendered. Sampling and culling matrices
-are required to determine the tessellation of a NURBS surface into line segments
-or polygons and to cull a NURBS surface if it lies outside the viewport.
-.IP
-If this mode is set to \%\f3GL_FALSE\fP, then the program needs
-to provide a projection matrix, a modelview matrix, and a viewport
-for the NURBS renderer to use to construct sampling and culling matrices.
-This can be done with the \%\f3gluLoadSamplingMatrices\fP function.
-This mode is initially set to \%\f3GL_TRUE\fP.
-Changing it from \%\f3GL_TRUE\fP to \%\f3GL_FALSE\fP does not affect
-the sampling and culling matrices until 
-\%\f3gluLoadSamplingMatrices\fP
-is called.
-.SH NOTES
-If \%\f3GLU_AUTO_LOAD_MATRIX\fP is true, sampling and culling may be
-executed incorrectly if NURBS routines are compiled into a display list.
-.P
-A \f2property\fP of 
-\%\f3GLU_PARAMETRIC_TOLERANCE\fP,
-\%\f3GLU_SAMPLING_METHOD\fP,
-\%\f3GLU_U_STEP\fP, or
-\%\f3GLU_V_STEP\fP,
-or a \f2value\fP of 
-\%\f3GLU_PATH_LENGTH\fP,
-\%\f3GLU_PARAMETRIC_ERROR\fP, 
-\%\f3GLU_DOMAIN_DISTANCE\fP 
-are only available if the GLU version is 1.1 or greater. They are not
-valid parameters in GLU 1.0. 
-.P
-\%\f3gluGetString\fP can
-be used to determine the GLU version. 
-.P
-\%\f3GLU_NURBS_MODE\fP is only availble if the GLU version is 1.3 or
-greater.
-.P
-The \%\f3GLU_OBJECT_PATH_LENGTH\fP and \%\f3GLU_OBJECT_PARAMETRIC_ERROR\fP

-\f2slices\fP
-Specifies the number of subdivisions around the \f2z\fP axis.
-.TP

-Specifies the number of concentric rings about the origin into which
-the partial disk is subdivided.

-\f2start\fP
-Specifies the starting angle, in degrees, of the disk portion.
-.TP
-\f2sweep\fP
-Specifies the sweep angle, in degrees, of the disk portion.
-.SH DESCRIPTION
-\%\f3gluPartialDisk\fP renders a partial disk on the $ z ~=~ 0 $ plane. A partial disk is 
-similar to a full disk, except that only the subset of the disk from
-\f2start\fP through \f2start\fP + \f2sweep\fP is included (where 0 degrees is along the 
-+\f2y\f axis,
-90 degrees along the +\f2x\fP axis, 180 degrees along the \-\f2y\fP axis, and 
-270 degrees along the \-\f2x\fP axis).
-.P
-The partial disk has a radius of 
-\f2outer\fP, and contains a concentric circular hole with a radius 
-of \f2inner\fP. If \f2inner\fP is 0, then no hole is generated. The partial disk is
-subdivided around the \f2z\fP axis into slices (like pizza slices), and also
-about the \f2z\fP axis into rings 
-(as specified by \f2slices\fP and \f2loops\fP, respectively).
-.P
-With respect to orientation, the +\f2z\fP 
-side of the partial disk is considered to 
-be outside (see \%\f3gluQuadricOrientation\fP).
-This means that if the 
-orientation is set to \%\f3GLU_OUTSIDE\fP, then any normals generated 
-point along the +\f2z\fP axis. Otherwise, they point along the \-\f2z\fP 
-axis.
-.P
-If texturing is turned on (with \%\f3gluQuadricTexture\fP), texture
-coordinates are generated
-linearly such that where $ r ~=~ "outer" $, the value at (\f2r\fP, 0, 0) is 
-(1.0, 0.5), at (0, \f2r\fP, 0) it is (0.5, 1.0), at (\-\f2r\fP, 0, 0) 
-it is (0.0, 0.5), and 
-at (0, \-\f2r\fP, 0) it is (0.5, 0.0).

-.SH DESCRIPTION
-\%\f3gluPerspective\fP specifies a viewing frustum into the world coordinate system.
-In general, the aspect ratio in \%\f3gluPerspective\fP should match the aspect ratio
-of the associated viewport. For example, $ "aspect" ~=~ 2.0 $ means

-Depth buffer precision is affected by the values specified for
-\f2zNear\fP and \f2zFar\fP.
-The greater the ratio of \f2zFar\fP to \f2zNear\fP is,

-.SH DESCRIPTION
-\%\f3gluPickMatrix\fP creates a projection matrix that can be used to restrict drawing
-to a small region of the viewport.
-This is typically useful to
-determine what objects are being drawn near the cursor.
-Use \%\f3gluPickMatrix\fP to
-restrict drawing to a small region around the cursor.
-Then,
-enter selection mode (with \f3glRenderMode\fP) and rerender the scene.
-All primitives that would have been drawn near
-the cursor are identified and stored in the selection buffer.
-.P
-The matrix created by \%\f3gluPickMatrix\fP is multiplied by the current matrix just
-as if \f3glMultMatrix\fP is called with the generated matrix.
-To effectively use the generated pick matrix for picking,
-first call \f3glLoadIdentity\fP to load an identity matrix onto the
-perspective matrix stack.
-Then call \%\f3gluPickMatrix\fP,
-and finally, call a command (such as \%\f3gluPerspective\fP)
-to multiply the perspective matrix by the pick matrix.
-.P
-When using \%\f3gluPickMatrix\fP to pick NURBS, be careful to turn off the NURBS 
-property
-\%\f3GLU_AUTO_LOAD_MATRIX\fP.  If \%\f3GLU_AUTO_LOAD_MATRIX\fP is not
-turned off, then any NURBS surface rendered is subdivided differently with
-the pick matrix than the way it was subdivided without the pick matrix.

-\%\f3gluPwlCurve\fP describes a piecewise linear trimming curve for a NURBS surface.
-A piecewise linear curve consists of a list of

-describes a curve in two-dimensional homogeneous (\f2u\fP, \f2v\fP,

-\f2data\fP is a pointer to a user-defined data structure. If the appropriate callback(s)

-\%\f3gluTessCallback\fP is used to indicate a callback to be used by a tessellation object.
-If the specified callback is already defined, then it is replaced. If 
-\f2CallBackFunc\fP is NULL, then the existing callback becomes undefined.
-.P
-These callbacks are used by the tessellation object to describe how a 
-polygon specified by the user is broken into triangles. Note that there 
-are two versions of each callback: one with user-specified polygon data 
-and one without. If both versions of a particular callback are specified, 
-then the callback with user-specified polygon data will be used. Note 
-that the \f2polygon_data\fP parameter used by some of the functions is
-a copy of the pointer that was specified when 
-\%\f3gluTessBeginPolygon\fP was called. The legal callbacks are as follows:
-.TP 10
-\%\f3GLU_TESS_BEGIN\fP
-The begin callback is invoked like \f3glBegin\fP to indicate the start of 
-a (triangle) primitive. The function takes a single argument of type
-GLenum. If the \%\f3GLU_TESS_BOUNDARY_ONLY\fP property is set to
-\%\f3GL_FALSE\fP, then the argument is set to either
-\%\f3GL_TRIANGLE_FAN\fP, \%\f3GL_TRIANGLE_STRIP\fP, or \%\f3GL_TRIANGLES\fP. If
-the \%\f3GLU_TESS_BOUNDARY_ONLY\fP property is set to \%\f3GL_TRUE\fP,
-then the argument will be set to \%\f3GL_LINE_LOOP\fP. The function
-prototype for this callback is:
-.RS
-.Ex
-void begin ( GLenum type );
-.Ee
-.RE
-.TP
-\%\f3GLU_TESS_BEGIN_DATA\fP
-The same as the \%\f3GLU_TESS_BEGIN\fP callback except that it 
-takes an additional pointer argument. This pointer is identical to the 
-opaque pointer provided when
-\%\f3gluTessBeginPolygon\fP was called. The function prototype for this callback
-is:
-.RS
-.Ex
-void beginData ( GLenum type, void *polygon_data );
-.Ee
-.RE
-.TP
-\%\f3GLU_TESS_EDGE_FLAG\fP
-The edge flag callback is similar to \f3glEdgeFlag\fP. The function
-takes a single boolean flag that indicates which edges lie on the
-polygon boundary. If the flag is \%\f3GL_TRUE\fP, then each vertex
-that follows begins an edge that lies on the polygon boundary, that is,
-an edge that separates an interior region from an exterior one.
-If the flag is \%\f3GL_FALSE\fP, then each vertex that follows begins an edge
-that lies in the polygon interior. The edge flag callback (if defined) is 
-invoked before the first vertex callback.
-.IP
-Since triangle fans and triangle strips do not support edge flags, the begin 
-callback is not called with \%\f3GL_TRIANGLE_FAN\fP or \%\f3GL_TRIANGLE_STRIP\fP
-if a non-NULL edge flag callback is provided. (If the callback is
-initialized to NULL, there is no impact on performance). Instead, the fans and
-strips are converted to independent triangles. The function prototype
-for this callback is:
-.RS
-.Ex
-void edgeFlag ( GLboolean flag );
-.Ee
-.RE
-.TP
-\%\f3GLU_TESS_EDGE_FLAG_DATA\fP
-The same as the \%\f3GLU_TESS_EDGE_FLAG\fP callback except that it takes an additional pointer
-argument. This pointer is identical to the opaque pointer provided when
-\%\f3gluTessBeginPolygon\fP was called. The function prototype for this callback
-is:
-.RS
-.Ex
-void edgeFlagData ( GLboolean flag, void *polygon_data );
-.Ee
-.RE
-.TP
-\%\f3GLU_TESS_VERTEX\fP
-The vertex callback is invoked between the begin and end callbacks.
-It is similar to \f3glVertex\fP, and it defines the vertices of the triangles 
-created by the tessellation process. The function
-takes a pointer as its only argument.  This pointer is identical to
-the opaque pointer provided by the user when the vertex was described
-(see \%\f3gluTessVertex\fP). The function prototype for this callback is:

-void vertex ( void *vertex_data );

-convex, concave or self-intersecting polygon. Within each \%\f3gluTessBeginPolygon\fP/\%\f3gluTessEndPolygon\fP

-\%\f3gluTessEndContour\fP reference pages for more details.
-.P
-Once \%\f3gluTessEndPolygon\fP is called, the polygon is tessellated, and the

-.SH DESCRIPTION
-\%\f3gluTessNormal\fP describes a normal for a polygon that the program is defining.
-All input data will be projected onto a plane perpendicular to one of 
-the three coordinate axes before tessellation and all output triangles
-will be oriented CCW with 
-respect to the normal (CW orientation can be obtained by reversing the
-sign of the supplied normal). For example, if you know that all polygons

-before rendering any polygons.
-.P
-If the supplied normal is (0.0, 0.0, 0.0) (the initial value), the normal is
-determined as follows. The direction of the normal, up to its sign, is
-found by fitting a plane to the vertices, without regard to how the
-vertices are connected. It is expected that the input data lies approximately
-in the plane; otherwise, projection perpendicular to one of the three
-coordinate axes may substantially change the geometry. The sign of the
-normal is chosen so that the sum of the signed areas of all input
-contours is nonnegative (where a CCW contour has positive area).
-.P
-The supplied normal persists until it is changed by another call to 
-\%\f3gluTessNormal\fP.

-\f2data\fP
-Specifies the value of the indicated property.
-.SH DESCRIPTION
-\%\f3gluTessProperty\fP is used to control properties stored in a tessellation object. These
-properties affect the way that the polygons are interpreted and rendered. 
-The legal values for \f2which\fP are as follows:
-.TP 15
-\%\f3GLU_TESS_WINDING_RULE\fP 
-Determines which parts of the polygon are on the "interior". 
-\f2data\fP may be set to one of \%\f3GLU_TESS_WINDING_ODD\fP,
-\%\f3GLU_TESS_WINDING_NONZERO\fP, \%\f3GLU_TESS_WINDING_POSITIVE\fP, or
-\%\f3GLU_TESS_WINDING_NEGATIVE\fP, or \%\f3GLU_TESS_WINDING_ABS_GEQ_TWO\fP.
-.IP
-To understand how the winding rule works, consider that the input 
-contours partition the plane into regions. The winding rule determines which
-of these regions are inside the polygon.
-.IP
-For a single contour C, the winding number of a point x is simply the signed
-number of revolutions we make around x as we travel once around C
-(where CCW is positive). When there are several contours, the individual
-winding numbers are summed. This procedure associates a signed integer 
-value with each point x in the plane. Note that the winding number is the
-same for all points in a single region.
-.bp
-.IP
-The winding rule classifies a region as "inside" if its winding number 
-belongs to the chosen category (odd, nonzero, positive, negative, or
-absolute value of at least two). The previous GLU tessellator (prior to
-GLU 1.2) used the "odd" rule. The "nonzero" rule is another common way to
-define the interior. The other three rules are useful for polygon CSG
-operations.
-.TP
-\%\f3GLU_TESS_BOUNDARY_ONLY\fP 
-Is a boolean value ("value" should be set
-to GL_TRUE or GL_FALSE). When set to GL_TRUE, a set of closed contours
-separating the polygon interior and exterior are returned instead of a 
-tessellation. Exterior contours are oriented CCW with respect to the
-normal; interior contours are oriented CW. The \%\f3GLU_TESS_BEGIN\fP
-and \%\f3GLU_TESS_BEGIN_DATA\fP callbacks use the type GL_LINE_LOOP for
-each contour.
-.TP
-\%\f3GLU_TESS_TOLERANCE\fP
-Specifies a tolerance for merging features to reduce the size of the output.
-For example, two vertices that are very close to each other might be
-replaced by a single vertex. The tolerance is multiplied by the largest
-coordinate magnitude of any input vertex; this specifies the maximum
-distance that any feature can move as the result of a single merge
-operation. If a single feature takes part in several merge operations, the
-total distance moved could be larger.
-.IP
-Feature merging is completely optional; the tolerance is only a hint.
-The implementation is free to merge in some cases and not in others, or to
-never merge features at all. The initial tolerance is 0.
-.IP
-The current implementation merges vertices only if they are exactly 
-coincident, regardless of the current tolerance. A vertex is spliced into
-an edge only if the implementation is unable to distinguish which side of
-the edge the vertex lies on. Two edges are merged only when both endpoints
-are identical.

-.SH DESCRIPTION
-\%\f3gluTessVertex\fP describes a vertex on a polygon that the program defines. Successive
-\%\f3gluTessVertex\fP calls describe a closed contour. For example, 
-to describe a quadrilateral \%\f3gluTessVertex\fP should be called four times.
-\%\f3gluTessVertex\fP can only be called between \%\f3gluTessBeginContour\fP and

-.P
-\f2data\fP normally points to a structure containing the vertex

-or \%\f3GLU_TESS_VERTEX_DATA\fP callback after tessellation 
-(see the \%\f3gluTessCallback\fP reference page).
-.SH EXAMPLE
-A quadrilateral with a triangular hole in it can be described as follows:
-.sp
-.Ex
-gluTessBeginPolygon(tobj, NULL);
- gluTessBeginContour(tobj);
-   gluTessVertex(tobj, v1, v1);

-   gluTessVertex(tobj, v7, v7);
- gluTessEndContour(tobj);
-gluTessEndPolygon(tobj);
-.Ee
-.sp
-.SH NOTES
-It is a common error to use a local variable for \f2location\fP or \f2data\fP and store
-values into it as part of a loop.
-For example:
-.Ex
-for (i = 0; i < NVERTICES; ++i) {
-  GLdouble data[3];
-  data[0] = vertex[i][0];
-  data[1] = vertex[i][1];
-  data[2] = vertex[i][2];
-  gluTessVertex(tobj, data, data);
-  }
-.Ee
-.P
-This doesn't work.
-Because the pointers specified by \f2location\fP and \f2data\fP might not be 
-dereferenced until \%\f3gluTessEndPolygon\fP is executed,
-all the vertex coordinates but the very last set could be overwritten
-before tessellation begins.
-.P
-Two common symptoms of this problem are consists of a single point
-(when a local variable is used for \f2data\fP) and a
-\%\f3GLU_TESS_NEED_COMBINE_CALLBACK\fP error (when a local variable is
-used for \f2location\fP).

-.SH DESCRIPTION
-\fBGLwDrawingArea\fP and \fBGLwMDrawingArea\fP are widgets suitable
-for OpenGL drawing.  They
-provide a window with the appropriate visual and colormaps needed for
-OpenGL, based on supplied parameters.  GLwDrawingArea and
-GLwMDrawingArea also provide
-callbacks for redraw, resize, input, and initialization.
-.PP
-GLwDrawingArea is not a part of any widget set, but depends only on Xt.
-GLwDrawingArea can be used with any widget set.  GLwMDrawingArea
-is identical to
-GLwDrawingArea except that it is a subclass of the Motif\(Tm widget
-class XmPrimitive and
-has resources and defaults suitable for use with Motif.  For example,
-GLwMDrawingArea provides the default Motif background and foreground colors
-for resources, and deals better with keyboard traversal.  Although the
-GLwDrawingArea widget can be used in a Motif program, it is recommended that
-GLwMDrawingArea be used instead.
-.PP
-Since both GLwDrawingArea and GLwMDrawingArea
-widgets behave almost identically, the
-remainder of this manual page will refer only to GLwDrawingArea, except when
-the behaviors differ.  Unless explicitly stated, all statements
-about GLwDrawingArea also apply to GLwMDrawingArea.
-.PP
-Among the information provided when creating a GLwDrawingArea is
-information necessary to determine the visual.  This may be provided
-in three ways, all of them through resources.  A specific visualInfo
-structure may be passed in.  (This visualInfo must have been obtained
-elsewhere; it is the application designer's responsibility to make
-sure that it is compatible with the OpenGL rendering done by the
-application).  Alternatively, an attribute list may be provided.  This
-attribute list is formatted identically to that used for direct open
-GL programming.  Finally, each attribute can be specified as an
-individual resource.  The latter method is the simplest, and is the
-only method that works from resource files.
-.PP
-In addition to allocating the visual, the GLwDrawingArea will also
-allocate the colormap unless one is provided by the application.  (If
-one is provided it is the application writer's responsibility to
-guarantee compatibility between the colormap and the visual).  If 
-an application creates multiple GLwDrawingAreas with the same visual, 
-the same colormap will be used.  (However the colormap
-will not be shared among separate applications).
-.PP
-Creating the widget does not actually create the window until it is
-realized, and consequently, the application should not perform any
-OpenGL operations
-to the window immediately after creation.  Instead the application
-must wait until after it has realized the window.  Alternatively, the
-\fBginit\fP callback may be used to indicate when the window has been
-created.  Upon receiving this callback, the application can perform
-all OpenGL initialization for the window, and can subsequently perform
-other operations on it.  The initialization is discussed in more
-detail below.
-.PP
-Applications select which GLwDrawingArea they are accessing using either
-\fBglXMakeCurrent\fP or the convenience function
-\fBGLwDrawingAreaMakeCurrent\fP which uses a widget instead of a
-display and window.  If there is only one GLwDrawingArea this need
-only be called once, however if there is more than one GLwDrawingArea
-it should be called at the start of each callback.
-Callbacks in this case include not only
-callbacks provided by the widget itself, but any other callback that
-leads to GL activity such as a timeout or a workproc.
-.PP
-If an application is using double buffering, it may call
-\fBGLwDrawingAreaSwapBuffers\fP instead of \fBglXSwapBuffers\fP.  This
-allows the use of the widget instead of the display and window.
-.ne 5
-.SS "GLwDrawingArea Classes"
-GLwDrawingArea inherits behavior and resources from the \fBCore\fP class.
-.br
-The class pointer is \fBglwDrawingAreaWidgetClass\fP.
-.br
-The class name is \fBGLwDrawingArea\fP.
-.PP
-.ne 5
-.SS "GLwMDrawingArea Classes"
-GLwMDrawingArea inherits behavior and resources from the
-\fBXmPrimitive\fP and \fBCore\fP classes.
-.br
-The class pointer is \fBglwMDrawingAreaWidgetClass\fP.
-.br
-The class name is \fBGLwMDrawingArea\fP.
-.sp 1
-.SS "New Resources"
-The following tables define a set of widget resources used by the programmer
-to specify data.  The programmer can also set the resource values for the 
-inherited classes to set attributes for this widget.  To reference a
-resource by name or by class in a .Xdefaults file, remove the \fBGLwN\fP or
-\fBGLwC\fP prefix and use the remaining letters.
-There are two tables included.  The first table includes resources
-that correspond directly to the attributes used by \fBglXChooseVisual\fP.
-As with \fBglXChooseVisual\fP, all Boolean resources default to FALSE
-and all integer resources default to 0, except redSize, greenSize and
-blueSize which default to 1.  These resources can all be
-set only at creation time, and are used to determine the visual.  If
-either the \fIGLwNattribList\fP or \fIGLwNvisualInfo\fP resource is
-set, these resources are ignored.  The specific meaning of these
-resources is discussed in the \fBglXChooseVisual\fP manual page and
-will not be discussed here.

-.IP "\fBGLwNallocateBackground\fP"
-If TRUE, the background pixel and pixmap will be allocated if
-appropriate using the newly calculated colormap and visual.  If FALSE,
-they will retain values calculated using the parent's colormap and
-visual.  Applications which wish to have X clear their background for
-them will usually set this to TRUE.  Applications clearing their own
-background will often set this to FALSE, although they may set this to
-TRUE if they query the background for their own use.  One reason to
-leave this resource FALSE is that if color index mode is in use this
-avoid using up a pixel from the newly allocated colormap.  Also, on
-hardware that supports only one colormap, the application may need to
-do more careful color allocation to avoid flashing between the OpenGL
-colormap and the default X colormap.
-(Note that because of the way Xt works, the background colors
-are originally calculated using the default colormap; if this resource
-is set they can be recalculated correctly.  If a colormap was
-explicitly supplied to the widget rather than being dynamically
-calculated, these resources are always calculated using that colormap.)
-.IP "\fBGLwNallocateOtherColors\fP"
-This is similar to \fBGLwNallocateBackground\fP, but allocates other
-colors normally allocated by widgets.  Although the GLwDrawingArea
-and GLwMDrawingArea widget do not make use of these colors the
-application may choose to query them.  For the non-Motif
-GLwDrawingArea widget there are no other colors allocated, so this
-resource is a no-op.  For the Motif GLwMDrawingArea are widget, the
-XmPrimitive resources \fBXmNforeground\fP, \fBXmNhighlightColor\fP,
-and \fBXmNhighlightPixmap\fP are calculated.
-.IP "\fBGLwNattribList\fP"
-Contains the list of attributes suitable for a call to
-\fBglXChooseVisual\fP.  If this resource is NULL, it is calculated
-based on the attribute resources.  If it is not NULL, the attribute
-resources are ignored.
-.IP "\fBGLwNexposeCallback\fP"
-Specifies the list of callbacks that is
-called when the widget receives an exposure event.
-The callback reason is \fBGLwCR_EXPOSE\fP.
-The callback structure also includes the exposure event.  The
-application will generally want to redraw the scene.
-.IP "\fBGLwNginitCallback\fP"
-Specifies the list of callbacks that is
-called when the widget is first realized.  Since no OpenGL operations can
-be done before the widget is realized, this callback can be used to
-perform any appropriate OpenGL initialization such as creating a context.
-The callback reason is \fBGLwCR_GINIT\fP.
-.IP "\fBGLwNinputCallback\fP"
-Specifies the list of callbacks that is
-called when the widget receives a keyboard
-or mouse event.  By default, the input callback is called on each key
-press and key release, on each mouse button press and release, and
-whenever the mouse is moved while a button is pressed.  However this
-can be changed by providing a different translation table.  
-The callback structure also includes the input event.
-The callback reason is \fBGLwCR_INPUT\fP.
-.IP ""
-The input callback is provided as a programming convenience, as it
-provides a convenient way to catch all input events.  However, a more
-modular program can often be obtained by providing specific actions and
-translations in the application rather than using a single catch all
-callback.  Use of explicit translations can also provide for more
-customization. 
-.IP "\fBGLwNinstallBackground\fP"
-If set to TRUE, the background is installed on the window.  If set to
-FALSE, the window has no background.  This resource has no effect
-unless \fBGLwNallocateBackground\fP is also TRUE.
-.IP "\fBGLwNinstallColormap\fP"
-If set to TRUE, the widget will call \fIXSetWMColormapWindows\fP to
-tell the window manager to install the colormap when the window's
-shell has focus.  If set to FALSE, this will not be called.  For
-applications with multiple GLwDrawingAreas sharing a single colormap,
-it is most efficient to set this resource to TRUE for exactly one
-GLwDrawingArea with each colormap.  If an application needs
-additional control over the order of colormaps, this resource can be
-set to FALSE, with the application calling \fIXSetWMColormapWindows\fP
-explicitly.
-.IP "\fBGLwNresizeCallback\fP"
-Specifies the list of callbacks that is
-called when the GLwDrawingArea is resized.
-The callback reason is \fBGLwCR_RESIZE\fP.
-.IP "\fBGLwNvisualInfo\fP"
-Contains a pointer to the window's visual info structure.  If NULL,
-the visualInfo is calculated at widget creation time based on the
-\fIGLwNattributeList\fP resource (which is itself calculated from the
-various resources).  If \fBGLwNvisualInfo\fP is not NULL the
-\fIGLwNattributList\fP and the attribute resources are ignored.
-.sp 1
-.SS "Inherited Resources"
-Both GLwDrawingArea and GLwMDrawingArea inherit behavior and resources
-from the core superclass.  Other than the behavior of the colormap and
-background resources described previously, all defaults are the same as
-for core.
-.PP
-In addition, the Motif version GLwMDrawingArea also inherits from XmPrimitive.
-The behavior of the color resources has been described previously.
-The \fITraversalOn\fP resource is disabled for this widget, but if
-keyboard input is required it should be enabled.  (Also, the
-application should call \fBXmProcessTraversal(widget, XmTRAVERSE_CURRENT)\fP
-whenever mouse button 1 is clicked in the widget.  This is similar to
-the requirements of the Motif Drawing area.)  Because Motif gets
-confused by having multiple visuals in one top level shell,
-\fBXmNhighlightOnEnter\fP has been disabled, and
-\fBXmNhighlightThickness\fP has been set to 0.
-.SS "Callback Information"
-A pointer to the following structure is passed to each callback:
-.sp 1

-.SH NOTES
-.PP
-When using the input callback to receive keyboard input, the keycode
-in the event must be converted to a KeySym.  Use
-\fBXLookupKeysym(3X)\fP or \fBXLookupString(3X)\fP to do the
-conversion.  Keyboard input can also be dealt using translations, in
-which case no such conversion is required.
-.PP
-Motif programmers should keep in mind that OSF uses virtual
-bindings and replaces some of the key bindings.  As a common example,
-if the ESC key is to be used to exit the program (as it often is in GL
-programs), the translation should specify <key>osfCancel instead of
-<key>Escape.
-.PP
-Motif programmers may also create a GLwMDrawingArea widget with the Motif
-style \fBGLwCreateMDrawingArea\fP.

-The Motif program need only differ by including
-\fBGLwMDrawingArea.h\fP instead of \fBGLwDrawingArea.h\fP and by creating a widget of type
-\fBGLwMDrawingAreaWidgetClass\fP instead of \fBGLwDrawingAreaWidgetClass\fP.  As an
-alternative, the Motif program could use \fBGLwCreateMDraw(3X)\fP instead.
-.sp 1
-.SH WARNINGS
-.PP
-If a GLwDrawingArea widget is created as a child of an already realized
-widget, the GLwDrawingArea widget will be created immediately, without giving
-the user an opportunity to add the \fBginit\fP callback.  In such a
-case, initialization should be done immediately after creating the
-widget rather than by using the callback.
-.PP
-If the non-Motif GLwDrawingArea widget is used in a Motif program and
-keyboard traversal is attempted, the behavior is undefined if the user
-traverses into the GLwDrawingArea widget.
