It is still fast in a sense, I'd say too. Can a cylinder be bent anywhere
along it's length for example? I'm thinking of Chris Colefax's nice include
for doing such things but it was of course slow and had the tendency to break
up.
If you can manage a nonuniform scaling effect (sphere into egg) with your
deform patch I want to see it in POV-Ray 3.5. Oh okay, version 4 then. :-)
