Don't need sprite coord origin per coord.
Also, don't need separate sprite enable bit - if all coords have it diabled,
then there are no point sprites (technically, there's a distinction in pre-GL3,
but it only differs in having more leniency in clamping to max size, something
the state tracker would need to handle and the hardware won't bother anyway).
Also, use packed field for the per-coord enables.
All in all, should save 3 dwords in rasterizer state (from 10 down to 7).
The state tracker is responsible for clamping to any graphics API enforced
size min/max limits for both the static point_size setting as well as per
vertex point size (in the vertex shader).
Note that mesa state tracker didn't actually use these values.
The current glCompressedTexImage support in the state tracker assumes
that compressed textures have minimal pitch.
However, in some cases this is not true, such as for mipmaps of non-POT
compressed textures on nVidia hardware.
This patch adds a check and does a memcpy for each line instead of the
whole image in that case.

Tweaks for C90 compilation.
the xorg state tracker really wants the driver to handle overlapping
blits, and r300 uses u_blitter for blits. This patch adds overlapping
blit support via a temporary surface when its required.
Explain how to build for windows. Both MSVC 9 and cross MinGW supported.
Stop documenting LLVM 2.5 as supported. It still supported at the moment
but it will soon stop being.
The call to _eglSwapBuffers is unnecessary, and the function is missing
when -fvisibility=hidden. Also remove the extraneous braces and indent
the block.
Everybody is using the C99's integer types. Everybody except Microsoft,
which in turns means everybody is including their own definitions of C99
integer types for MSVC, causing duplicate definitions when linking two
projects. This is the case of building Gallium and LLVM with MSVC.
Shipping alternative stdint.h and stdbool.h headers for MSVC allows us
to share a single definition. It also removes clutter from the Gallium
headers.
When static libraries are created from other archives, objects are
extracted and then deleted when the static library is done. This can
race when there are multiple static libraries being created from the
same archives as with libmesa.a and libmesagallium.a.
Should fix this issue with parallel jobs:
make[5]: *** No rule to make target
> `../../../../../../src/mesa/libmesagallium.a', needed by
> `radeon_dri.so'. Stop
