Comment(by remic):

 I don't know if it is in the spec,
 but ValidateTopology doesn't check edge-linking (that is, that for each
 edge, next_left_edge and next_right_edge are correct).

 We could use a function I wrote on the whole topology:
 rc_RecomputeEdgeLinking(topology_name TEXT, nodes_to_update INT[] ).
 If it returns something, it means there were errors (that were corrected).

 I'm not sure either that ValidateTopology check that left_face and
 right_face are correctly set.
