This one's for me.

You'll want to call the function: set_wuv in
First argument is the number of verts (could easily be
Second argument is the new face, then the vertex flags
(explained in the nice ascii drawing in the fonction's
body) and then the pinned face (original face
containing pinned uvs flags and the like).

To use the function correctly, you have to call it
with the proper vertex flags AND also set the f1 flag
for each edge that is being cut. This sets the factor
of where the cut is along the edge starting from the
first vertex in the edge (0.0) to the last (1.0)
stored in a short (multiplied by 32768).
