From 2009! Yeah, I had a sneaking feeling that I was 'rediscovering the use of
fire', ha, and that someone had already done this kind of thing. I guess I
should have done a newsgroup search-- but I was too excited about my 'brand-new
use for POV-ray'  :-P

Infinite gradients, "inserting a user-made gradient", egads!

Actually, I was beginning to think about this in a hazy sort of way, that the
object pattern itself (as turned into a function) was the root of the problem,
because of it's strict 'inside/outside' nature. As-is, it doesn't behave like a
normal function, from what I can tell.

I just downloaded Bill P's files; will definitely give them a read. BTW, I think
this is the first time that I have ever downloaded and un-packed a Unix tar.gz
'thing'. I learn something new every day.

Thanks a bunch!
