Simple mesh before and after the collapse of edge `e`.
Simple mesh before and after the collapse of edge `v-w` into vertex `w`. While the normals of `f1`and `f2` are almost equal, they are opposed after the edge collapse.

The class `Bounded_normal_change_placement` is a placement that checks if
another placement inverts the normal of a face around the stars of the
two vertices of an edge that is candidate for an edge collapse.
