Fun fact to know: POV-Ray (post-3.7.0) should be fine with more than 256
entries in a whatever_map.

Good to know - but besides UberPOV, when we'll see an official version?

You mean an official /release/ version?
Can't say. That'll be up to Chris Cason.
I for one consider POV-Ray an ongoing work in progress anyway, now that
it's on GitHub. Whatever is in the "master" branch should be good enough
to go.

By the way, you can avoid the warning messages by deleting 'rgb' before
eval_pigment () in the macro.

useful technique. Thanks for re-discovering, enhancing and posting the
code.
