After splitting out the i810 driver into its own legacy directory, we
can identify the common routines not as i830 but as intel. This
clarifies the code which *is* i830 specific.

Fixes:
Bug 28446 - Garbled Font with Mathematica 7
https://bugs.freedesktop.org/show_bug.cgi?id=28446
Rewriting the glyphs to render to the destination directly and removing
the more expensive multiple invocations of CompositePicture per picture
was a great performance boost -- except that it needs special handling
in the backend in order to not fallback. Having done so for i915, I
neglected to ensure the sanity checking in i965_prepare_composite() was
sufficient. As it turns out, it was not and so we misrendered CA-glyphs
when rendering directly to the destination. This causes us to fallback
properly, but is a performance regression as we no longer try the 2-pass
magic helper before resorting to s/w. At the moment, I'd rather live
with the temporary regression and fix i965 to do the same magic as i915,
as it critical to fixing the severe performance issues currently
crippling i965, as I believe that this regression only affects the
minority of applications (incorrect, as it turns out, as the glyphs are
overlapping) rendering directly to the destination.

If the destination cannot fit into the 3D pipeline when we need to
composite, we fallback to doing the operation on the CPU. This is very
slow, and quite easy to trigger on i915 by plugging in an external
display.
An alternative is to extract the extents of the operation from the
destination using the blitter which can usually handle much larger
operations. This gives us a temporary target that can fit into the 3D
pipeline and thus be accelerated, before copying back into the larger
real destination.
For x11perf this boosts glyph rendering on PineView, from 38kglyphs/s to
480kglyphs/s. Just a little shy of the native performance of 601kglyphs/s

Bug 28135 - [855GM] Slowdown/High CPU-Usage after Git-Commit
926fbc7d90ac1d0d49d154f136f9c9ed613c98c2
https://bugs.freedesktop.org/show_bug.cgi?id=28135
The simple answer is that I had assumed that 0 was a reserved value.
However, without the bbp encoded into the format 0 was used for a8r8g8b8
and r5g6b5, which are very common formats!
The other possibility for the slowdown is that gtkperf is using of the
now verboten xrgb formats -- but would in fact be valid if the source
covers the clip and we could fixup the alpha value in the fixed function
combine.

We no longer workaround the lack of alpha expansion for xrgb textures as
this interferes with EXTEND_NONE, though we could if we know the source

x11perf regression caused by 2D driver
https://bugs.freedesktop.org/show_bug.cgi?id=28047
caused by
commit a7b800513fcc94e063dfd68d2f63b6bab7fae47d
uxa: Extract sub-region from in-memory buffers.
The issue is that as we extract the region prior to checking whether the
composite can in fact be accelerated, we perform expensive surplus
operations. This is particularly noticeable for ComponentAlpha text,
such as rgb10text. The solution here is to rearrange the
check_composite() prior to acquiring the sources, and only extracting
the subregion if the render path can not actually handle the texture.
Performance (on PineView):
a7b800513^: aa=68600 glyphs/s, rgb=29900 glyphs/s
a7b800513: aa=65700 glyphs/s, rgb=13200 glyphs/s
now: aa=66800 glyph/s, rgb=28800 glyphs/s
The residual lossage seems to be from the extra function call and
dixPrivate lookups. Hmm. More warning is the extremely low performance,
however the results are consistent so the improvement looks real...

Do not try to fixup the alpha in the ff/shaders as this has the
side-effect of overriding the alpha value of the border color, causing
images to be padded with black rather than transparent. This can
generate large and obnoxious visual artefacts.

This should restore the previous level of synchronisation between
textures and pixmaps, but *does not* guarantee that a texture will be
flushed before use. tfp should be fixed so that the ddx can submit the
batch if required to flush the pixmap.
A side-effect of this patch is to rename intel_batch_flush() to
intel_batch_submit() to reduce the confusion of executing a batch buffer
with that of emitting a MI_FLUSH.
Should fix the remaining rendering corruption involving tfp [inc compiz]:

Since batch buffers are rarely emitted by themselves but as part of a
sequence of state and vertices, the whole sequence is emitted atomically.
Here we just enforce that batches are marked as being part of an atomic
sequence as appropriate.

# single operation;
Option "DebugFlushCaches" "1" # Include a MI_FLUSH at the end of every
# batch buffer to force data to be

This is the beginning of the campaign to remove some of the absurd use of
Hungarian in the driver. Not that I don't like Hungarian, but I don't need
to know that pI830 is a pPointer.

We've talked about doing this since the start of the project, putting it off
until "some convenient time". Just after removing a third of the driver seems
like a convenient time, when backporting's probably not happening much anyway.

Currently when asked to composite using a gradient source or mask, we
fallback to using fbComposite(). This has the side-effect of causing a
readback on the destination surface, stalling the GPU pipeline. Instead,
like uxa_trapezoids(), we can use pixman to fill a scratch pixmap and then
copy that to an offscreen pixmap for use with uxa_composite().
