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.

See bug 16866.

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.
2009-04-28swrast: add missing break in clamp_rect_coord_linear()Brian Paul

Also, clean up the logic involved in choosing per-vertex vs. per-fragment primary+secondary color addition.
2009-04-06swrast: fix incorrect arithmetic for GL_ADD_SIGNED/GL_COMBINE4_NV modeBrian Paul
2009-04-06swrast: fix texture border color interpretationBrian Paul
The texture border color must be interpreted according to the texture's base format. For example, for a GL_ALPHA texture, sampling the border color should return (0,0,0,borderAlpha). This wasn't an issue here until I removed the legacy texenv code (we always use the combiner path now).
2009-04-03mesa: remove the noClamp parameter to _mesa_pack_rgba_span_float()Brian Paul
It was only set to GL_TRUE in one place where it isn't really needed (glGetTexImage(sRGB format)).
