* Checkpoint for GLSL compiler changes.Brian2006-12-136-61/+76
| | | | | | In brief: Check for enabled fragment program by looking at ctx->FragmentProgram._Current. New code for varying variables.

* make use of Parameters->StateFlags in _swrast_update_fragment_program()Brian Paul2006-10-311-7/+4
|
* We need to call _mesa_load_state_parameters() whenever a fragment programBrian Paul2006-10-312-6/+15
| | | | | | is enabled and we've changed any GL state that might be referenced by a fragment program (such as state.fog.params). Do this during swrast validation, not in _swrast_exec_fragment_program().
* In TEX instructions, use precomputed lambda only if using fragment.texcoord[k]Brian Paul2006-10-311-34/+33
| | | | | to sample texture[k]. Use zero otherwise. Not foolproof, but a good compromise.
* For TEX instructions use lambda=0. When sampling from texture unit K weBrian Paul2006-10-311-44/+71
| | | | | | | | | | were using the partial derivatives of texcoord[K] but the coordinate used for texture sampling may be something totally different (and texcoord[K] might not be a real texture coord at all). Net result was a bogus LOD is sometimes used, often resulting in using the smallest mipmap level (a constant color). Just use zero for now (undef LAMBDA_ZERO to override). Plus, some additional debug code.

* Don't pass x/y/width/height to ctx->Driver.Accum().Brian Paul2006-10-182-7/+11
| | | | | Compute the region after we've locked (and possibly updated the buffer's size). Same thing is needed for ctx->Driver.Clear().
