Loading PolyMeshes to OpenFlipper results in unusable normals with values INF/NAN
Load a polymesh with a non-convex polygon (attached) and the halfedge normals as they are stored in OpenMesh are unusable.
Normals are set to value -1.#INF. This doesn't happen for triangle meshes or poly meshes in which all polygons are convex.
