This restores the behaviour of Mesa 6.5.1, fixing a regression in 6.5.2.
See bug 9345. Revisit someday...

fragment program (such as state.fog.params). Do this during swrast
validation, not in _swrast_exec_fragment_program().

to sample texture[k]. Use zero otherwise. Not foolproof, but a good
compromise.

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.

Added some INLINE hints.

Compute the region after we've locked (and possibly updated the buffer's size).
Same thing is needed for ctx->Driver.Clear().

Add support for runtime colorbuffer types.

Fix bugs in apply_aa_coverage().

Save/restore array->ChanType in case colors are converted.
