* mesa: increase max texture image units and GLSL samplers to 16Brian Paul2008-12-311-26/+27
| | | | | | | | | | | | | | | | The max texture coord units is still 8. All the fixed-function paths are still limited to 8 too. But GLSL shaders can use more samplers now. Note that some texcoord-related data structures are declared to be 16 elements in size rather than 8. This just simplifies the code in a few places; the extra elements aren't accessible to the user. These changes haven't been extensively tested yet, but sanity checking has been done. It should be possible to increase the max image units/samplers to 32 without doing anything special. Beyond that we'll need longer bitfields in a few places.

* mesa: add gl_program::Input/OutputFlags[] arrayBrian Paul2008-11-241-0/+2
| | | | | These arrays will indicate per-input or per-output options for vertex/fragment programs such as centroid-sampling and invariance.

* mesa: refactor: move #define FEATURE flags into new mfeatures.h fileKeith Whitwell2008-09-211-35/+4
| | | | | | | | | | | | | Also, check the FEATURE flags in many places. (cherry picked from commit 40d1a40f294f1ed2dacfad6f5498322fc08cc2d1) Conflicts: src/mesa/main/config.h src/mesa/main/context.c src/mesa/main/texobj.c src/mesa/main/texstate.c src/mesa/main/texstore.c

* Updated GLSL uniform/sampler handling from gallium-0.1 branchBrian Paul2008-05-141-0/+1
| | | | | | | | | | Previously, the shader linker combined the uniforms used by the vertex and fragment shaders into a combined set of uniforms. This made the implementation of glUniform*() simple, but was rather inefficient otherwise. Now each shader gets its own set of uniforms (no more modelview matrix showing up in the fragment shader uniforms, for example). cherry-picked by hand from gallium-0.1 branch
