Since we're reusing buffers we're effectively transforming all
of them into dynamic buffers.
It would be nice to not cache long lived static buffers. But there
is no way to detect the long lived from short lived ones yet. A
good heuristic would be buffer size.
The texture owns the surface handle. All derivatives need to keep
a reference to texture.
This fixes several assertions failures starting up Jedi Knight 2.
Should cause no change for DRM surface sharing -- reference count still
done as before there.
Strict aliasing tule violations were fixed on master, but
they're still causing problem in this branch, so disable this assumptions.
Do not apply this fix to master (revert when you merge).
It turns out that 965 and friends cannot actually render to an xRGB
surfaces. Instead, the surface has to be RGBA with writes to alpha
disabled and the blend function modified to always use 1.0 for
destination alpha.
Back when we were flushing the entire batch at BindFramebuffer, the kernel
would notice the domain transition when someone went to texture from it and
flush for us. We no longer do the batch flushing every time, so we get to
do aggressive flushing until we move batchbuffer handling to libdrm.
Fixes piglit fbo-flushing. Bug #25377. No noticeable performance loss
on cairo-gl (so this is better than batch flushing).
The assertion is that the correct read type to be using is the native
type of the underlying read renderbuffer. For some fallback paths, this
may be worse than GL_RGBA/GL_UNSIGNED_BYTE for reads today, but it gets
all drivers the expected GL_BGRA/GL_UNSIGNED_BYTE for ARGB8888 or
GL_BGR//GL_UNSIGNED_SHORT_5_6_5_REV for rgb565 with no work.
This fixes the intel (and other) DRI drivers to report read formats that
should hit blit PBO readpixels paths.
First time around render targets are not enabled yet (done in
r700SendRenderTargetState) so blend state is not emitted for any targets.
Affects first glClear in some mesa tests.
As a quick fix reorder state emit so that target is set first

To fix the confilicts in projtex.c and glxinfo.c I just took the code from
mesa_7_6_branch. The conflicts seem to have occured from cherry-picks from
mesa_7_7_branch to mesa_7_6_branch followed by commmits just to
mesa_7_6_branch.
