In my case, this must not be true. I iterate over a triangulation
using a the facet iterator. If a facet fullfills a criterion I add it
to my list of points and facets and later they get inserted into a
Polyhedron. As you can see, it is possible to happen, that there are
faces which are not of the same orientation. What can I do? Fixing
every face is going to be an intensive task which I want to avoid
if possible.
