Description

A `GeoFace` is a collection of vertices and normals. Those vertices are supposed to live in the same plane. To get the correct triangulation and face orientation, we need to sort those vertices. Right now, the sort algorithm works with the vertices projection over the plane `z = 0`. This may work for most of the cases, but it will not cover any face which is over a normal plane to `z = 0`.

Research direction

Start by locating the GeoFace implementation and the current vertex-sort algorithm that projects vertices onto z = 0. Trace how the sorted vertices feed triangulation and face orientation. Done means faces on arbitrary planes are sorted consistently without relying on the z = 0 projection; the issue names no files or tests to run.
