I'm glad to know it's possible, even if I can't use it yet. If Steve does a Mac version of UVMapper Pro, maybe he'll be receptive to the idea of including an automatic algorithm to do the edge-spreading, so that both sides of the figure template will be spread out evenly. One projection-mapping analogy might be "equal-area projection". The camel on the left of ElectricAardvark's attachment appears to use ordinary planar mapping (orthogonal perspective mapping), so all the edge polygons are shrunken in the direction along which they were projected onto the 2D plane.
