Wine tends to pessimistically use ~0 for its max index, but r300s
only can go up to 2^24-1, causing the kernel checker to freak out.
Civ4 is marginally improved now. Still crashes, but not as bad.
All the texture wrap modes are now implemented for linear and nearest
sampling.
However, texture border color is not yet supported so some wrap modes
will produce int coords outside the texture bounds. We'll get garbage
values insted of the texture border color for now.
The lp_int_type() function was creating an unsigned type. So rename
that function to lp_uint_type() and create new lp_int_type() that
creates a signed type.
This now passes piglit testcases, and shows performance improvements
on openarena. Blit-heavy apps may see degradation, but the
expectation is that the common case of 3D rendering will see
significant wins.
This regresses gen-teximage on my 855, and no piglit tests on my 945.
Promote the llvmpipe winsys more or less unchanged to
state_trackers/sw_winsys.h.
Some minor breakages:
- softpipe::texture_blanket is broken, but scheduled for removal anyway.
- haven't fixed up g3vdl yet.
The break in the __DRI_ATTRIB_RENDER_TYPE case was accidentally
removed in commit 5cf2c5851b. This puts
it back.

Only tested this on my rv530 with R300_NO_TCL=1, but it works there
at least. It would be nice to fix the tex_offset by chaning the vertex
program on tcl to read from offset 6 but this isn't really necessary.

at least on the r500 we get a lockup unless I do this, the compiler
seems to fail to compile and we just get a null fp.

I wasn't careful enough when removing support for GCC versions earlier
than 3.3.0. I could have sworn that I compile tested before pushing,
but apparently not. FAIL.

Mesa now requires GCC 3.3.0 or later. See the following thread from
the mesa3d-dev mailing list for more details:

Check if the native blit formats are supported, if not,
attempt to use an alternate format.
Skip 3, >4 bpp as per comments from mcencora on irc.
