* New SWspanarrays attribs[] array.Brian2007-02-0116-171/+140
| | | | | | | Replace texcoord[], varying[], etc. arrays with single attribs[] array, indexed by FRAG_ATTRIB_* values. Eliminates need to copy data into fragment program machine input registers. Will lead to future clean-ups.

* 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.
