Comment(by strk):

 note that azimuth is used to order edge ends around a node. There's
 probably a more robust way to do that (as done in GEOS/JTS) but before
 going there it'll be useful to remove some code duplication (the same
 azimuth-based code is in ST_AddEdgeModFace and ST_AddEdgeNewFace, and a
 similar one is in GetNodeEdges)
