035b21f365 i965: make brw_wm_prog_key a little smaller 
GLushort is big enough for the swizzle and origin fields.
The key could probably be made smaller still by re-ordering things.
I'll hold off on that until after the outputswritten64 branch is merged.
The key will get a little larger again with the GLbitfield64 fields.

4b377ae292 i915: Correct and make use of the defines for 32-bit depth texture modes. 
Previously, S8_Z24 depth textures would always be treated as intensity.

861fec163c i965: avoid shader translation on window resize 
If the fragment shader doesn't use FRAG_ATTRIB_WPOS (gl_FragCoord) we
don't need to worry about the window size and origin in
brw_wm_populate_key().

This avoids re-generating the i965 shader code when a window is resized.

Issue spotted by Keith Whitwell.

198ec96d36 i965: define, use BRW_MAX_DRAW_BUFFERS 
i965 might support more than 4 color draw buffers.  But if not, this protects
from breakage if the Mesa limit is raised.

f8f40b53a6 i915: Implement min/max LOD clamping with the hardware. 
This gets us expected behavior for clamping between mipmap levels, and
avoids relayout of textures for doing clamping.

92e7c6a258 i965: Fix fallout from ARB_depth_clamp enablement that broke glDepthRange. 
If a backwards glDepthRange was supplied (as with the old Quake no-z-clearing
hack), the hardware would have always clamped because we weren't clamping to
the min of near/far and the max of near/far.  Also, we shouldn't be clamping
to near/far at all when not in depth clamp mode (this usually didn't matter
since near/far are usually the same as the 0.0, 1.0 clamping you do for
fixed-point depth).

This should fix funny depth issues in PlaneShift, and fixes piglit
depth-clamp-range

32ec3f2673 mesa: Mostly fix swrast's ARB_depth_clamp support. 
I'd written a testcase for the hard part of the extension enablement, so
naturally the easy stuff was completely broken.  There are still issues,
as I'm seeing FLOAT_TO_UINT(max_f) == 0x0 when max_f == 1.0, but it gets
piglit depth-clamp-range closer to success.

6eb6a0e9cb intel: Don't bother MI_FLUSHing on glFlush in the DRI2 case. 
We only need it when drawing to the front buffer, which we never do for
DRI2.  No significant performance difference, but the flush is definitely
gone from the end of every batchbuffer.
