* i965: fix bugs in projective texture coordinatesBrian Paul2009-06-165-20/+54
| | | | | | | | | | | | | | | | | | | | | | | | For the TXP instruction we check if the texcoord is really a 4-component atttibute which requires the divide by W step. This check involved the projtex_mask field. However, the projtex_mask field was being miscalculated because of some confusion between vertex program outputs and fragment program inputs. 1. Rework the size_masks calculation so we correctly set bits corresponding to fragment program input attributes. 2. Rename projtex_mask to proj_attrib_mask since we're interested in more than just texcoords (generic varying vars too). 3. Simply the indexing of the size_masks and proj_attrib_mask fields. 4. The tracker::active[] array was mis-dimensioned. Use MAX_PROGRAM_TEMPS instead of a magic number. 5. Update comments, add new assertions. With these changes the Lightsmark demo/benchmark renders correctly, until we eventually hit a GPU lockup...
* softpipe: fix out of bounds quad rasterization bugBrian Paul2009-06-161-3/+6
| | | | | | | | For some triangles we can generate quads which lie just outside the surface bounds. Just check the quad's mask before trying to emit/process the quad. Fixes failed assertion in Lightsmark.
* mesa: fix incorrect viewport clamping in _mesa_set_viewport()Brian Paul2009-06-161-2/+2
| | | | | A 0 by 0 viewport size is legal. Don't clamp against lower bound of one. The error checking earlier in the function prevents negative values.
* mesa: fix REMAINDER() macroBrian Paul2009-06-161-1/+1
| | | | | The results were incorrect for some negative values of A. See bug 21872.

* softpipe: Fix softpipe_is_texture_referenced.José Fonseca2009-06-154-0/+22
| | | | | | | | | Render results are only visible when the render cache is flushed. softpipe_is_texture_referenced must reflect that or transfers to/from the textures bound in the framebuffer won't be proceeded of the necessary flush, causing transfer data to be outdated/clobbered. This fixes conform drawpix test with softpipe.
* progs/tests: Use opaque colors.José Fonseca2009-06-151-2/+2
| | | | | Transparency is not relevant for this example, and leads to distraction due to different results in alpha visuals, when capturing images to disk.

* demos: update fbotexture.c to use EXT or ARB functions exclusivelyBrian Paul2009-06-122-38/+77
| | | | | | | | | When the -arb option is specified we use GL_ARB_framebuffer_object intead of GL_EXT_framebuffer_object. For some vendors' OpenGL it's important to call the ARB entrypoints instead of the EXT entrypoints to get correct behaviour. Use some function pointer tricks to do this (instead of GLEW).

* mesa: rework vertex shader output / fragment shader input attribute matchingBrian Paul2009-06-111-20/+33
| | | | | | | | | | | | | | | | | | | | Before, if a vertex shader's outputs didn't exactly match a fragment shader's inputs we could wind up with invalid TGSI shader declarations. For example: Before patch: DCL OUT[0], POSITION DCL OUT[1], COLOR[1] DCL OUT[2], GENERIC[0] DCL OUT[3], GENERIC[0] <- note duplicate [0] DCL OUT[4], GENERIC[2] After patch: DCL OUT[0], POSITION DCL OUT[1], COLOR[1] DCL OUT[2], GENERIC[0] DCL OUT[3], GENERIC[1] DCL OUT[4], GENERIC[2]
