2009-09-21swrast: fix cube face selectionBrian Paul
If arx and ary are equal, we still want to choose from one of them, and not arz. This is the same as Michal's softpipe fix.

2009-09-08mesa: Add support for ARB_depth_clamp.Eric Anholt
This currently doesn't include fixing up the cliptests in the assembly paths to support ARB_depth_clamp, so enabling depth_clamp forces the C path.
2009-09-03swrast: wrap comment to 80 columns, remove dead codeBrian Paul
2009-09-03mesa: consolidate PBO map/unmap helpersBrian Paul
Instead of _mesa_map_readpix_pbo() use _mesa_map_pbo_source(). Instead of _mesa_map_drawpix_pbo() and _mesa_map_bitmap_pbo() use _mesa_map_pbo_dest().
2009-08-31swrast: fix selection/feedback regressionBrian Paul
This fixes a conform selection/feedback regression introduced by commit 8f4d66c5f893b49eb3973aa3b31a856314c045c7
2009-08-31swrast: can't use deferred texture/shading if using KIL instructionBrian Paul
If the fragment program uses KIL, we have to execute it before z/stencil testing. Otherwise, deferred texture/shading lets us skip shading for pixels that fail z/stencil testing.

Same change as for softpipe
2009-08-12Merge branch 'new-frag-attribs'Brian Paul
This branch introduces new FRAG_ATTRIB_FACE and FRAG_ATTRIB_PNTC fragment program inputs for GLSL gl_FrontFacing and gl_PointCoord. Before, these attributes were packed with the FOG attribute. That made things complicated elsewhere.

2009-07-31swrast: fix incorrect texcoord attribute testBrian Paul
2009-07-29mesa: add new FRAG_ATTRIB_FACE and FRAG_ATTRIB_PNTC fragment program inputsBrian Paul
Previously, the FOGC attribute contained the fragment fog coord, front/back- face flag and the gl_PointCoord.xy values. Now each of those things are separate fragment program attributes. This simplifies quite a few things in Mesa and gallium. Need to test i965 driver and fix up point coord handling in the gallium/draw module...

2009-11-17Merge branch 'outputswritten64'Ian Romanick
Add a GLbitfield64 type and several macros to operate on 64-bit fields. The OutputsWritten field of gl_program is changed to use that type. This results in a fair amount of fallout in drivers that use programs. No changes are strictly necessary at this point as all bits used are below the 32-bit boundary. Fairly soon several bits will be added for clip distances written by a vertex shader. This will cause several bits used for varyings to be pushed above the 32-bit boundary. This will affect any drivers that support GLSL. At this point, only the i965 driver has been modified to support this eventuality. I did this as a "squash" merge. There were several places through the outputswritten64 branch where things were broken. I foresee this causing difficulties later for bisecting. The history is still available in the branch.

2009-06-10swrast: fix state validation bug for changing program constantsBrian Paul
Add _NEW_PROGRAM_CONSTANTS to _SWRAST_NEW_DERIVED. This makes sure that we update the fragment shader's constants when state vars (such as point size) changes. Fixes the progs/glsl/points.c demo.
2009-06-03swrast: always do span clipping in _swrast_write_rgba_span()Brian Paul
It's possible for mis-behaving vertex programs to produce vertex data with very large/NaN values. This doesn't get handled reliably by the clipper code so we may try to rasterize triangles that extend beyond the viewport/window. Always clip spans to avoid invalid memory accesses later.
2009-05-12swrast: update/restore the opt_sample_rgb/rgba_2d() functionsBrian Paul
2009-05-07mesa: move the NullBufferObj from GLcontext to gl_shared_stateBrian Paul
Since shared array objects may point to the null/default buffer object, the null/default buffer object should be part of the shared state.
2009-05-07swrast: fix span clipping bugBrian Paul
If a horizontal span of pixels was located at x < 0 we could sometimes read/write outside of renderbuffer bounds.
