Based uppon a patch from Pali Rohár <pali.rohar@gmail.com>.
This seems to get at least YUV->RGB conversion working.
So a simple "mplayer -vo vdpau" now seems to work fine.
According to OpenGL 3.1 chapter 2.1.5 the representation without zero
should only be used for vertex attribute values, but not for textures
or frame-buffers.

i965: Remove "TXD" from justification of sampler message headers.
The coordinate offsets set in the m1 header are for textureOffset;
they have nothing to do with textureGrad (TXD).

i965/gen7: Add support for rendering to depthbuffer mipmap levels > 0.
The same as 3e43adef95 but for Gen7.
This doesn't quite fix GL_ARB_depth_texture/fbo-clear-formats; there's
still a 1 pixel wide black line on the right edge of the smaller squares.
The results were entirely wrong before, and are at least close now.

Since wayland 4bde293ff8 we cant
lookup visuals, as we dont receive the visual token events.
The format for pixmap-images thus has to default to argb for now.
mesa: Emit definition of GLAPIENTRYP in es_generator.py.
GLES uses GL_APIENTRYP instead of GLAPIENTRYP, which breaks with the
latest API table generation code. This fixes the issue by emitting a
definition for GL_APIENTRYP when generating the GLES files.
gallivm: Fix for dynamically linked LLVM 2.8 library.
This prevents the error
prog: for the -disable-mmx option: may only occur zero or one times!
when creating a new context after XCloseDisplay with DRI drivers linked
with a shared LLVM 2.8 library.
mesa: fix vertex array enable checking in check_valid_to_render()
In particular, this fixes the case where a vertex shader only uses
generic vertex attributes (non-0th). Before, we were no-op'ing the
glDrawArrays/Elements().
This fixes the new piglit pos-array test.
NOTE: This is a candidate for the 7.10 branch.
mesa: handle some srgb cases in the fast path in _mesa_get_teximage
Previously, always did unorm8->float/nonlinear-to-linear conversion (using
lookup table), then convert back to nonlinear (using the expensive math
func pow among others), and finally convert back to int (assuming caller
wants unorm8), because the float texture fetch function is used for getting
the actual texel values. This should probably all be changed at some point,
but for now simply enable the memcpy path also for srgb formats (but if for
instance swizzling is required, still the whole conversion will be done).
Clip distance is calculated each time vertex position is written
which is suboptiomal is some cases but very safe.
User clip planes are an obsolete feature anyway.
Every time number of clip planes increases, the vertex program
is recompiled.
That ensures no overhead in normal case (no user clip planes)
and reasonable overhead otherwise.
Fixes 3D windows in compiz, and reflection effect in neverball.
Also fixes compiz expo plugin when windows were dragged and each
window shown 3 times.
i965: Stop caching the combined depth/stencil region in brw_context.c.
This was going to get in the way of separate depth/stencil (which
wants to know about both, and whether they are the same rb), and also
wasn't a sufficient flag for the fix in the following commit.
i965/fs: Fix GPU hang on texture2d-bias on pre-Ironlake.
In the 16-wide rework, I missed that we were setting some things to be

i965: Add support for correct GL_CLAMP behavior by clamping coordinates.
This removes the stupid strict-conformance fallback code I broke when

i965/fs: Drop the viewport index/rtai clearing in gen6 fb writes.
These fields are documented to be in the payload, and though the FB
write docs say they *aren't* in the payload, for all other fields the
payload and header is structured so that no overwriting is required
except for non-default options.
i965/fs: Add support for "if" statements in 16-wide mode on gen6+.
It turns out there's nothing in the hardware preventing this. It
appears that it ought to work on pre-gen6 as well, but just produces
GPU hangs.
Improves glbenchmark Egypt framerate 4.4% +/- 0.3% (n=3), and Pro by
2.6% +/- 0.6% (n=3).

As of gen6, alt-mode (which we use) MOVs of floats are not raw --
they'll modify infs/nans. This broke discard and alpha test in
16-wide, where apparently the upper 8 bits of the pixel enables being
set were causing the whole value to get trashed upon being moved.
Treating the values as UD instead of float makes sure they get
preserved. While I'm here, replace the two 8-wide moves of the halves
of the header with a single compressed move.

i965/gen6: Fix blending state when no color buffer is bound.
This is part of fixing fbo-alphatest-nocolor -- a regression in
35e8fe5c99 after the initial regression,
that had us using a garbage BLEND_STATE[0] (in particular, the alpha
test enable) if no color buffer was bound.
i965/fs: Cut an instruction and a temporary from gen6 discard statements.
I thought I was thwarted initially when I couldn't do conditional mod
on a MOV, and couldn't use two immediate constants in one instruction.
But g0 != g0 is also a way to produce a failing comparison.
