 The order by is there, but is based on minx/miny of bounding box, which in
 this case are the same (ouch). The annoying thing is that any ordering
 serves predictability but not performance. Anyway, when an added edge
 splits 2 faces... _which_ face should we add first ? For the
 AddEdgeModFace function we retain the right face, maybe for symmetry we
 should _add_ the right face first in the AddEdgeNewFace..
