+
+2015-06-06  Ashish Azad  <ashish.azad@samsung.com>
+
+	Fix Savannah bug #45260.
+
+	* src/pfr/pfrdrivr.c (pfr_get_kerning): Fix typo.
+
+2015-06-03  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Fix memory leak.
+
+	Problem reported by Grissiom <chaos.proton@gmail.com>; in
+
+	  http://lists.nongnu.org/archive/html/freetype/2015-05/msg00013.html
+
+	there is an example code to trigger the bug.
+
+	* src/truetype/ttobjs.c (tt_size_init_bytecode): Free old `size'
+	data before allocating again.  Bug most probably introduced four
+	years ago in version 2.4.3.
+
+2015-06-02  Werner Lemberg  <wl@gnu.org>
+
+	[raster] Add more tracing.
+
+	* src/raster/ftraster.c (FT_TRACE7) [_STANDALONE_]: Define.
+	(Vertical_Sweep_Span, Vertical_Sweep_Drop, Horizontal_Sweep_Span,
+	Horizontal_Sweep_Drop, Render_Glyph): Add tracing calls.
+
+2015-06-01  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] While tracing opcodes, show code position and stack.
+
+	* src/truetype/ttinterp.c: Change all existing TRACE7 calls to
+	TRACE6.
+	(opcode_name): Add string lengths.
+	(TT_RunIns): Implement display of code position and stack.
+
+2015-05-31  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] In GX, make private point numbers work correctly.
+
+	This is completely missing in Apple's documentation: If a `gvar'
+	tuple uses private point numbers (this is, deltas are specified for
+	some points only), the uncovered points must be interpolated for
+	this tuple similar to the IUP bytecode instruction.  Examples that
+	need this functionality are glyphs `Oslash' and `Q' in Skia.ttf.
+
+	* src/truetype/ttgxvar.c (tt_delta_shift, tt_delta_interpolate,
+	tt_handle_deltas): New functions.
+	(TT_Vary_Get_Glyph_Deltas): Renamed to...
+	(TT_Vary_Apply_Glyph_Deltas): ... this; it directly processes the
+	points and does no longer return an array of deltas.
+	Add tracing information.
+	Call `tt_handle_deltas' to interpolate missing deltas.
+	Also fix a minor memory leak in case of error.
+
+	* src/truetype/ttgxvar.h: Updated.
+
+	* src/truetype/ttgload.c (TT_Process_Simple_Glyph,
+	load_truetype_glyph): Updated.
+
+2015-05-31  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] In GX, make intermediate tuplets work at extrema.
+
+	* src/truetype/ttgxvar.c (ft_var_apply_tuple): Fix range condition.
+
+2015-05-31  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Add tracing information to GX code.
+
+	* src/truetype/ttgxvar.c (ft_var_load_avar, ft_var_load_gvar,
+	ft_var_apply_tuple, TT_Get_MM_Var, TT_Set_MM_Blend,
+	TT_Set_Var_Design, tt_face_vary_cvt): Do it.
+
+2015-05-28  Werner Lemberg  <wl@gnu.org>
+
+	* src/tools/apinames.c (names_dump): Fix invalid reference.
+
+	Problem reported by Guzman Mosqueda, Jose R
+	<jose.r.guzman.mosqueda@intel.com>.
+
+2015-05-24  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Fix commit from 2015-05-22.
+
+	* src/truetype/ttgload.c, src/truetype/ttinterp.c: Guard new code
+	with `TT_CONFIG_OPTION_SUBPIXEL_HINTING'.
+
+	Problem reported by Nikolaus Waxweiler <madigens@gmail.com>.
+
+2015-05-23  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Fix return values of GETINFO bytecode instruction.
+
+	* src/truetype/ttinterp.h (TT_ExecContextRec): New fields
+	`vertical_lcd' and `gray_cleartype'.
+
+	* src/truetype/ttgload.c (tt_loader_init): Initialize new fields.
+	Change `symmetrical smoothing' to TRUE, since FreeType produces
+	exactly this.
+
+	* src/truetype/ttinterp.c (Ins_GETINFO): Fix selector/return bit
+	values for symmetrical smoothing, namely 11/18.
+	Handle bits for vertical LCD subpixels (8/15) and Gray ClearType
+	(12/19).
+
+2015-05-23  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Minor.
+
+	* src/truetype/ttinterp.h (TT_ExecContext):
+	 s/subpixel/subpixel_hinting.
+
+	* src/truetype/ttgload.c, src/truetype/ttgload.h: Updated.
+
+2015-05-22  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Support selector index 3 of the INSTCTRL instruction.
+
+	This flag activates `native ClearType hinting', disabling backwards
+	compatibility mode as described in Greg Hitchcocks whitepaper.  In
+	other words, it enables unrestricted functionality of all TrueType
+	instructions in ClearType.
+
+	* src/truetype/ttgload.c (tt_get_metrics): Call `sph_set_tweaks'
+	unconditionally.
+	(tt_loader_init): Unset `ignore_x_mode' flag if bit 2 of
+	`GS.instruct_control' is active.
+
+	* src/truetype/ttinterp.c (Ins_INSTCTRL): Handle selector index 3.
+	(Ins_GETINFO): Updated.
+
+	* docs/CHANGES: Document it.
+
+2015-05-20  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Minor.
+
+	* src/truetype/ttinterp.h (SetSuperRound): Fix type of `GridPeriod'
+	argument.
+
+2015-05-17  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Fix loading of composite glyphs.
+
+	* src/truetype/ttgload.c (TT_Load_Composite_Glyph): If the
+	ARGS_ARE_XY_VALUES flag is not set, handle argument values as
+	unsigned.  I trust `ttx' (which has exactly such code) that it does
+	the right thing here...
+
+	The reason that noone has ever noticed this bug is probably the fact
+	that point-aligned subglyphs are rare, as are subglyphs with a
+	number of points in the range [128;255], which is quite large (or
+	even in the range [32768;65535], which is extremely unlikely).
+
+2015-05-12  Chris Liddell  <chris.liddell@artifex.com>
+
+	[cff] Make the `*curveto' operators more tolerant.
+
+	* src/cff/cf2intrp.c (cf2_interpT2CharString): The opcodes
+	`vvcurveto', `hhcurveto', `vhcurveto', and `hvcurveto' all iterate,
+	pulling values off the stack until the stack is exhausted.
+	Implicitly the stack must be a multiple (or for subtly different
+	behaviour) a multiple plus a specific number of extra values deep.
+	If that's not the case, enforce it (as the old code did).
+
+2015-05-12  Chris Liddell  <chris.liddell@artifex.com>
+
+	[cff] fix incremental interface with new cff code.
+
+	* src/cff/cf2ft.c (cf2_getSeacComponent): When using the incremental
+	interface to retrieve glyph data for a SEAC, it be left to the
+	incremental interface callback to apply the encoding to raw
+	character index (as it was in the previous code).
+
+2015-04-29  Alexei Podtelezhnikov <apodtele@gmail.com>
+
+	[autofit] Speed up IUP.
+
+	* src/autofit/afhints.c (af_iup_interp): Separate trivial snapping to
+	the same position from true interpolation, use `scale' to reduce
+	divisions.
+
+2015-04-28  Werner Lemberg  <wl@gnu.org>
+
+	[cff] Use `name' table for PS name if we have a SFNT-CFF.
+
+	This follows the OpenType 1.7 specification.  See
+
+	  http://tug.org/pipermail/tex-live/2015-April/036634.html
+
+	for a discussion.
+
+	* src/cff/cffdrivr.c (cff_get_ps_name): Use the `sfnt' service if we
+	have an SFNT.
+
+2015-04-27  Alexei Podtelezhnikov <apodtele@gmail.com>
+
+	[truetype] Speed up IUP.
+
+	* src/truetype/ttinterp.c (_iup_worker_interpolate): Separate trivial

+
+	[raster] Fix Savannah bug #44022.
+
+	Add fallback for glyphs with degenerate bounding boxes.
+
+	If a glyph has only one very narrow feature, the bbox can end up
+	with either the width or height of the bbox being 0, in which case
+	no raster memory is allocated and no attempt is made to render the
+	glyph.  This is less than ideal when the drop-out compensation in
+	the rendering code would actually result in the glyph being
+	rendered.
+
+	This problem can be observed with the `I' glyph (gid 47) in the
+	Autodesk RomanS TrueType font.
+
+	* src/raster/ftrend1.c (ft_raster1_render): Add a fallback if either
+	dimension is zero to explicitly round up/down (instead of simply
+	round).
+
+2015-01-17  Werner Lemberg  <wl@gnu.org>
+
+	Add some tools to handle yearly copyright notice updates.
+
+	We are now following the GNU guidelines: A new release automatically
+	means that the copyright year of all affected files gets updated; it
+	is no longer used to track years of modification changes.
+
+	* src/tools/update-copyright-year: New Perl script.
+	* src/tools/update-copyright: New shell script that calls
+	`update-copyright-year' on all files.
+	* src/tools/no-copyright: Exceptions that should not be handled by
+	`update-copyright'

+	[autofit] Add embedded array of segments and edges.
+
+	Avoids multiple mallocs per typical glyphs.
+
+	With this and recent changes to avoid mallocs, the thread-safe

+	cached singleton.

+
+	[autofit] Allocate hints object on the stack.
+
+	This avoids one malloc per load.
+
+	* src/autofit/afloader.h (AF_LoaderRec): Change type of `hints' to
+	`AF_GlyphHints'.
+	Update prototype.
+
+	* src/autofit/afloader.c (af_loader_init): Use `AF_GlyphHints'

+	(af_loader_load_g): Updated.
+
+	* src/autofit/afmodule.c (af_autofitter_load_glyph): Use local
+	`hints' object.
+
+2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
+
+	[autofit] Reuse slot glyph loader.
+
+	No need to create a new glyph loader; we can reuse the one from
+	`slot->internal->loader'.  It's hard to tell why it was written that
+	way originally, but new code looks sound and correct to me, and
+	avoids lots of allocations.
+
+	* src/autofit/afloader.c (af_loader_init): Change return type to
+	`void'.
+	Don't call `FT_GlyphLoader_New'.
+	(af_loader_reset): Don't call `FT_GlyphLoader_Rewind'.
+	(af_loader_load_g): Update code to use `internal->loader', which
+	doesn't need copying of data.
+
+	* src/autofit/afloader.h (AF_LoaderRec): Remove `gloader' member.
+	Update prototype.
+
+	* src/autofit/afmodule.c (af_autofitter_load_glyph): Updated.
+
+2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
+
+	[autofit] Remove (unused) support for composite glyphs.
+
+	We never have to deal with composite glyphs in the autohinter, as
+	those will be loaded into FORMAT_OUTLINE by the recursed
+	`FT_Load_Glyph' function.
+
+	In the rare cases that FT_LOAD_NO_RECURSE is set, it will imply
+	FT_LOAD_NO_SCALE as per `FT_Load_Glyph', which then implies
+	FT_LOAD_NO_HINTING:
+
+	  /* resolve load flags dependencies */
+
+	  if ( load_flags & FT_LOAD_NO_RECURSE )
+	    load_flags |= FT_LOAD_NO_SCALE         |
+	                  FT_LOAD_IGNORE_TRANSFORM;
+
+	  if ( load_flags & FT_LOAD_NO_SCALE )
+	  {
+	    load_flags |= FT_LOAD_NO_HINTING |
+	                  FT_LOAD_NO_BITMAP;
+
+	    load_flags &= ~FT_LOAD_RENDER;
+	  }
+
+	and as such the auto-hinter is never called.  Thus, the recursion in
+	`af_loader_load_g' never actually happens.  So remove the depth
+	counter as well.
+
+	* src/autofit/afloader.c (af_loader_load_g): Remove `depth'
+	parameter.
+	<FT_GLYPH_FORMAT_COMPOSITE>: Remove associated code.
+	(af_loader_load_glyph): Updated.
+
+2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
+
+	[raster] Fix uninitialized memory access.
+
+	Apparently `ras.cProfile' might be uninitialized.  This will be the
+	case if `ras.top == ras.cProfile->offset', as can be seen in
+	`End_Profile'.  The overshoot code introduced in a change `Fix B/W
+	rasterization of subglyphs with different drop-out modes.' (from
+	2009-06-18) violated this, accessing `ras.cProfile->flags'
+	unconditionally just before calling `End_Profile' (which then
+	detected that `cProfile' is uninitialized and didn't touch it).
+
+	This was harmless, and was not detected by valgrind before because
+	the objects were allocated on the `raster_pool', which was always
+	initialized.  With recent change to allocate raster buffers on the
+	stack, valgrind now reported this invalid access.
+
+	* src/raster/ftraster.c (Convert_Glyph): Don't access an
+	uninitialized `cProfile'.
+
+2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
+
+	[smooth] Fix uninitialized memory access.
+
+	Looks like `ras.span_y' could always be used without initialization.
+	This was never detected by valgrind before because the library-wide
+	`raster_pool' was used for the worker object and `raster_pool' was
+	originally zero'ed.  But subsequent reuses of it were using `span_y'
+	uninitialized.  With the recent change to not use `render_pool' and
+	allocate worker and buffer on the stack, valgrind now detects this
+	uninitialized access.
+
+	* src/smooth/ftgrays.c (gray_raster_render): Initialize
+	`ras.span_y'.
+
+2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
+
+	[base] Don't initialize unused `driver->glyph_loader'.
+
+	* src/base/ftobjs.c (Destroy_Driver): Don't call

+	(FT_Add_Module): Don't call `FT_GlyphLoader_New'.
+
+2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
+
+	[base] Don't allocate `library->raster_pool' anymore.
+
+	It's unused after the following commits:
+
+	  [raster] Allocate render pool for mono rasterizer on the stack.
+	  [raster] Remove 5-level gray AA mode from monochrome rasterizer.
+
+	The value of FT_RENDER_POOL_SIZE still serves the purpose it used to
+	serve, which is, to adjust the pool size.  But the pool is now
+	allocated on the stack on demand.
+
+	* src/base/ftobjs.c (FT_New_Library, FT_Done_Library): Implement.
+
+2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
+
+	[base] Do not reorder library->renderers upon use.
+
+	Instead of keeping `library->renderers' in a MRU order, just leave
+	it as-is.  The MRU machinery wasn't thread-safe.
+
+	With this patch, rasterizing glyphs from different faces from
+	different threads doesn't fail choosing rasterizer
+	(FT_Err_Cannot_Render_Glyph).
+
+	Easiest to see that crash was to add a `printf' (or otherwise let
+	thread yield in FT_Throw with debugging enabled).
+
+	* src/base/ftobjs.c (FT_Render_Glyph_Internal), src/base/ftoutln.c
+	(FT_Outline_Render): Don't call `FT_Set_Renderer'.
+
+2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
+
+	[raster] Allocate render pool for mono rasterizer on the stack.
+
+	Instead of using the `render_pool' member of `FT_Library' that is
+	provided down to the rasterizer, completely ignore that and allocate
+	needed objects on the stack instead.
+
+	With this patch, rasterizing glyphs from different faces from
+	different threads doesn't crash in the monochrome rasterizer.
+
+	* src/raster/ftraster.c (black_TRaster): Remove `buffer',
+	`buffer_size', and `worker' members.
+
+	(ft_black_render): Create `buffer' locally.
+	(ft_black_reset): Updated.
+
+2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
+
+	[raster] Remove 5-level gray AA mode from monochrome rasterizer.
+
+	It was off by default and couldn't be turned on at runtime.  And the
+	smooth rasterizer superceded it over ten years ago.  No point in
+	keeping.  Comments suggested that it was there for compatibility
+	with FreeType 1.
+
+	550 lines down.
+
+	* src/raster/ftraster.c (FT_RASTER_OPTION_ANTI_ALIASING,
+	RASTER_GRAY_LINES): Remove macros and all associated code.
+
+	(black_TWorker): Remove `gray_min_x' and `gray_max_x'.
+	(black_TRaster): Remove `grays' and `gray_width'.
+
+	(Vertical_Sweep_Init, Vertical_Sweep_Span, Vertical_Sweep_Drop,
+	ft_black_render): Updated.
+
+	* src/raster/ftrend1.c (ft_raster1_render): Simplify code.
+	(ft_raster5_renderer_class): Removed.
+
+2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
+
+	[smooth] Allocate render pool for smooth rasterizer on the stack.
+
+	Instead of using the `render_pool' member of `FT_Library' that is
+	provided down to the rasterizer, completely ignore that and allocate
+	needed objects on the stack instead.
+
+	With this patch, rasterizing glyphs from different faces from
+	different threads doesn't crash in the smooth rasterizer.

+2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
+
+	[truetype] Allocate TT_ExecContext in TT_Size instead of TT_Driver.
+
+	Previously the code had stipulation for using a per-TT_Size exec
+	context if `size->debug' was true.  But there was no way that
+	`size->debug' could *ever* be true.  As such, the code was always
+	using the singleton `TT_ExecContext' that was stored in `TT_Driver'.
+	This was, clearly, not threadsafe.
+
+	With this patch, loading glyphs from different faces from different
+	threads doesn't crash in the bytecode loader code.
+
+	* src/truetype/ttobjs.h (TT_SizeRec): Remove `debug' member.
+	(TT_DriverRec): Remove `context' member.
+
+	* src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Remove

+
+	[autofit] Allocate AF_Loader on the stack instead of AF_Module.
+
+	Stop sharing a global `AF_Loader'.  Allocate one on the stack during

+
+	Right now this results in about 25% slowdown, to be fixed in a
