| * 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.

| | | | | | | | | | 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to/from the textures bound in the framebuffer won't be proceeded of the necessary flush, causing transfer data to be outdated/clobbered.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.

* | i965: handle OPCODE_SWZ in the glsl pathRoland Scheidegger2009-06-161-0/+1
| | | | | | | | | | | | glsl compiler will not generate OPCODE_SWZ, and as a first step it would be translated away to a MOV anyway (why?), but later internally this opcode is generated (for EXT_texture_swizzling).

| * | mesa: implement GL_ARB_map_buffer_rangeBrian Paul2009-06-088-13/+265
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Only enabled for software drivers at this point. Note that the gl_buffer_object::Access enum field has been replaced by a gl_buffer_object::AccessFlags bitfield. The new field is a mask of the GL_MAP_x_BIT flags which is a superset of the old GL_READ_ONLY, GL_WRITE_ONLY and GL_READ_WRITE modes. When we query GL_BUFFER_ACCESS_ARB we translate the bitfield into the conventional enum values.

* | | mesa: revert some recent VBO buffer object refcounting changesBrian Paul2009-06-152-8/+3
| | | | | | | | | | | | | | | | | | | | | | | | Reverts part of commit d7ea9ddf5824556e47decac7ba200f37cf1e552f. We were calling _mesa_reference_buffer_object() on some heap-allocated memory that was uninitialized and could trigger an assertion. We can actually go back to "looser" ref counting of the Null/default buffer object in these cases.

| * | 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).

| | | | | | | | | | | | | | | | | | | | | ...rather than with linear interpolation. Modern hardware should use perspective-corrected interpolation for colors (as for texcoords). glHint(GL_PERSPECTIVE_CORRECTION_HINT, mode) can be used to get linear interpolation if mode = GL_FASTEST.
