It is a modification to SpectralComposer.pov, which I also converted to a .inc
file because I prefer that to modifying a library file for each project.  Should
I email it to you?

And I see that's also on your to-do list, although UberPOV /may/ make that job
easier.

That would certainly be faster than doing it with SDL.  However, I'm not sure
that the wrap-around that often happens with POV-Ray pigment functions won't
thwart that when the entire render is a giant pigment function.  (Otherwise,
couldn't we do the gamut mapping in post-processing as well?)
