Yes, you never know.

entities.fill_from_mesh(mesh, true, 2 | 8) is working nicelly, but a small gotcha..

---

%(#FF0000)[mesh.add_polygon(1,2,3)
mesh.add_polygon(2,3,4)]

Does gives hard edges, as expected.

%(#FF0000)[mesh.add_polygon(1,-2,3)
mesh.add_polygon(-2,3,4)]

gives hard soft edge between Points 2, as expected.

but so does this:

%(#FF0000)[mesh.add_polygon(1,2,3)
mesh.add_polygon(-2,3,4)]

or

%(#FF0000)[mesh.add_polygon(1,-2,3)
mesh.add_polygon(2,3,4)]

So I'm starting to see some trouble with this method. To be able to stear edge visibility one need to use 2 Points in comparison. For ex a Collection of edge.start and end positions.
For a triangulated quad this works but not if the face has innerloops,
Or faces where triangulation is splitting the face without hitting innerloops.

Was to fast here..
The docs actually explains this behavior, "value of [-1, 2, 3] indicates that the edge from 1 to 2 is hidden"
