The idea is to create vertices along the coarse edges once, without splitting coarse edges on separate ptex faces. This requires some indexing magic, vertices within a patch are no longer sequential. Not sure how to make it nicer without such a black magic looking calculations (which are basically boiling down to mimicking order of verts/edges creation). In the current offsets calculation loose verts and edges are not properly taken into account, but those are causing topology refiner to fail anyway, so it needs a bit deeper change.
