-----------
uv stitch static island highlight ported to bmesh system.
Unfortunately since we are missing a way to tesselate uvs, the result will look good only on concave faces since we are essentially using a triangle fan to draw. When a tesselation of uv polygons is possible the tool should also change to use that instead. This will also influence the preview drawing code, coming next.
