From what I can see, the fog distance is computed per-vertex and
stored in the FogCoord vertex shader output. There is no fragment
shader change required. The fixed-function vertex program hasn't been
converted to the GLSL IR yet, only the fragment program, which is
irrelevant here.

I only see implementation for ffvertex_prog.c
Wasn't (or will soon be) the FF->Mesa IR replaced with FF->GLSL IR? If so, can
you truly enable unconditionally on gallium/st?

If there are no other concerns, I'll push this on Saturday, including
the nv20 fix from Francisco Jerez.

The NV_fog_distance extension allows you to specify how the fog distance
of a fragment is calculated. The usual method approximates the distance
of the fragment from the eye as the absolute value of the distance of
the fragment from the eye's Z plane. (Or, rather, the distance of each
vertex and th
