Hm. Might be an option. I'll have to experiment a little how POV-Ray handles
various things with functions, pigments and image-maps to see if it does
work with the other scripts I'm trying to implement.

What I wanted to do was to create functions from images, to allow
transparency-mapping, gamma-correction, color-correction and a few basic
compositing/masking steps, so that I could do my compositing in POV-Ray. :-)

I'm not sure if layered textures will work properly with what I have in
mind, I had hoped that there was some simple way to "disable" the
alpha-channel from TGA and PNG (aside of running it through a function to
extract rgb).

Thanks anyway,
regards,
Tim
