We have all discussed the issue many times without answering the
following question:

How *hard* would it be to "fix" pov to eliminate the plateuas that exist
in the noise3d function?

I think that someone once said that pov used an unorthodox interval in
setting up its noise, something like [0,1.0] when the rest of the world
uses [-0.5,0.5], or vice versa.

If this were the case, could one simply change a half dozen CHARACTERS
and fix the problem?

Noise3d is my favorite function for a number of reasons, and those
plateaus are bugging me!
