* \brief Flip an edge.
*
* The original FlipEdge operator required both faces of the input edge
* to be triangles (and to be set). This version does not have such requirement.
* Either or both faces can be polygonal, the org and dest of the edge
* is then "rotated" around the big polygon that would exist if the two faces
* of the edge e were joined.
