Here are the results of an unrolling strategy I've had in mind for awhile. I
finally sat down and finished it. A generalized version of the scene file is in
p.b.s-f. I didn't implement this a macro because of it's dependence on the
camera. You really need the whole scene file.

This can be useful for several things, but primarily the results can be used as
a background image in a paint program to help align texture details when
cylindrically or spherically mapping objects not supporting UV-mapping. You
could also use it to support uv-mapping 'in reverse' (so to speak) if you use it
as a target in an image morphing package (i.e. Hijaak Morph)
