Comment(by vbraun):

 I thought about adding lines to the "empty face", but I decided against
 it. There are certainly arguments for both. But in the end I decided
 against it because only lines would not be representable by a polyhedron.
 I don't have any reference, though.

 When I refactor the `Pohlyhedron` class for ppl then I'll try to make
 `PolyhedronFace` derive from it. But right now its not feasible.

 I'll include your other suggestions and will post a patch in a couple of
 days.
