Good idea, but...

I've considered this, but texture mapping is (like all textures in
POVRAY) a procedural thing.  It's got to conform to (some)
pre-determined mathematical formula.
What I'm looking for is more like a bump map, but instead of perturbing
the surface normals, the function perturbs the specularity.


Thanks anyways....
