--- Comment #1 from Ilia Mirkin <imirkin at alum.mit.edu> ---
One thing to note is that the shaders don't *actually* use the functionality.
They all have the same copy & pasted adapter which makes glsl look more like
hlsl, and it includes some functions which call the various texture functions.
However they don't actually get used, at least in the few shaders I've looked

It may be sufficient to provide the prototypes but then fail at link-time. This
should allow the glsl compiler to optimize those functions out and thus work.
But I haven't checked -- perhaps there are in fact vertex shaders that try to
call texture2D(bias) or textureLod() from fp.
