I'm trying to script an outline operation in the uv geometry of an object. I need to move the uv edges slightly in some direction. Only the visible edges. I'm having a hard time figuring how to check some geometric info about edges, their visibility and points contiguous to others in the unwrap_uvw. What I'm trying to do is similar to the outline operation in a closed spline, in the uv geometry of an object. In splines, al the edges move in a perpendicular way, to the outside (or inside) of the object.
I hope I´ve explained my problem properly. Excuse my English.
