There seems to be some confusion by certain parties as to what UV Mapping actually is.
UV Mapping is a shorthand representation of a group of polygons (emphasis mine) belonging to one object layer so that they all are visible as a flatened 2d group in a square space that uses two coordinates: U and V.
UV Mapping is mesh specific, that is, while some can talk about a figure, "sharing" mapping, but what's actually happening is two totally different transformations from 3d to 2d that end up having the same basic shape. This is actually a new and different uv map, by definition, since it involves different polygons. It's not even the same instantiation of the original uv map, and therefore it can't be considered a derivative work since uv mapping projects 3d polygons onto 2d space, and with different polygons you have a completely different mapping even if the projection has the same general shape.
