This extension allows a client to bind one context in multiple threads
simultaneously. It is then up to the client to manage synchronization of
access to the GL, just as normal multithreaded GL from multiple contexts
requires synchronization management to shared objects.
The old value, BRW_SAMPLER_MESSAGE_SIMD8_SAMPLE makes it sound like we're
doing a non-bias texture lookup. It has the same value as the new constant
BRW_SAMPLER_MESSAGE_SIMD8_SAMPLE_BIAS_COMPARE, so there should be no
functional changes.
There is an issue with gcc 4.6.0 that leads to segfault/assert with mesa
due to ureg_src size, reshuffling the structure member to better better
alignment work around the issue.

7.9 + 7.10 candidate

so far only hw mipmap generation is testing on softpipe,
passes test added to piglit.
this requires another patch to mesa to let array textures mipmaps
even start to happen.
platform.system in SCons on Cygwin includes the OS version number.
Windows XP - CYGWIN_NT-5.1
Windows Vista - CYGWIN_NT-6.0
Windows 7 - CYGWIN_NT-6.1
Reduce all Cygwin platform variants to just 'cygwin' so anything
downstream can simply use 'cygwin' instead of the different full
platform names.
255.875 matches the hardware documentation. Presumably this was a typo.
NOTE: This is a candidate for the 7.10 branch, along with
commit 2bfc23fb86.

In the case where glBlitFramebuffer is being used to copy to a texture
without scaling it is faster if we can use the hardware to do a blit
rather than having to do a texture render. In most of the drivers
glCopyTexSubImage2D will use a blit so this patch makes it check for
when glBlitFramebuffer is doing a simple copy and then divert to
glCopyTexSubImage2D.
This was originally proposed as an extension to the common meta-ops.
However, it was rejected as using the BLT is only advantageous for Intel
hardware.

Might be necessary if a block sneaks in somewhere, like a common
block for moves of phi sources after a loop break.
This is harmless and normally will be removed before emission.
In linear scan we can't allocate multiple values with different
live ranges at the same time to assign them consecutive regs.
Maybe we should just switch to graph coloring for all values ...
The svga_update_state() mechanism is inadequate as it will always end up
flushing the primitives before processing the SVGA_NEW_COMMAND_BUFFER
dirty state flag.

If we fall back to software rendering due to the render target being
absent (GPU hang or other error in creating the named target), then we
do not need to nor should we wait upon the results.
