====================
SeparateIslands
While the algorithm should theoretically handle any collection
of triangles, there are speed and stability benefits to making
it work on as small a list as possible, so separate disconnected
collections of edges and process separately.
FIXME: we need to separate the source triangles before
doing this, because PointInSourceTris() can give a bad answer if
the source list has triangles not used in the optimization
