Convert Cg shaders with hlsl2glslfork ?

[rdb]

Here it is, by the way:

cg2glsl

By request, I hacked up a little script that uses cgc (part of the NVIDIA Cg Toolkit) to transpile a Cg shader to GLSL. It remaps inputs from Cg-style to GLSL-style. Not all inputs are converted correctly (eg. fog and material inputs aren’t converted at present), but most shaders I tried work fine. If you find one that doesn’t, let me know.
