Tests glBlitFramebuffer() between two texture/renderbuffer surfaces.
In particular, blit from level[1] of a cube map face to a 2D texture.
Used to find/fix bug in intel do_copy_texsubimage().

intel: fix src offset bug in do_copy_texsubimage()
Use src->draw_offset intead of zero. Zero usually worked, except when
the src renderbuffer is actually a texture mipmap level higher than zero.
Fixes progs/test/blitfb.c test.
Revert "i965: fix hacked Fallback usage in brw_prepare_vertices()"
This reverts commit 8810b8f671.
It turns out the i965 driver uses the intel->Fallback field as a boolean,
not as a bitmask. The intelFallback() function is a no-op in the i965
driver. It would have been nice if there were some comments about this.
I'll fix that next...
intel: fix GL state bugs in intel_texture_bitmap()
Need to push texture state and polygon state too.
Fixes rendering glitches seen in progs/demos/engine when changing
the rendering mode (wireframe, texture modes).
This makes bitmap rendering a little slower, unfortunately.
Some cards have crippling defaults set and use only 4
of 32 lanes. This should activate 16 on these.
Those that allow 32 by default should still do so.

mesa: choose texture format in core mesa, not drivers
Call the ctx->Driver.ChooseTextureFormat() function from core Mesa's
_mesa_[Copy]TexImage functions instead of in the driver functions.
One less thing for drivers to do.
llvmpipe: Fast path for sampling rgba8 textures with linear filtering.
Implement Keith's suggestion of doing most of the sampling with 16x8
and 8x16 AoS, and only doing the conversion to floating point SoA at
the very last step.
Improves gloss performance by 10%.
