Okay, I've figured out how to use image maps to apply pre-existing images
to POV objects as surface pigments. And I've figured out the difference
between the three currently available image map types.

What I can't figure out is how to apply an image map to an irregular shape
without distorting portions of the image. I want to take a .gif (an actual
map of the world, not that it matters) and put it on an object (a map, of
course) laying in a drawer, such that part of it is laying flat within the
drawer, part of it curls up over the faceplate of the drawer, and the rest
is hanging down out of the drawer.

The obvious problem is that the various surfaces of the map object are at
severe angles to one another. When I try to apply the image map, whichever
surface was upright (facing the z-axis) will get mapped properly, and all
the rest gets distorted.

Can anyone help me with this?
