forceSharedVertices after convertToFlatShadedMesh is rearranging vertices (indexes?)

I’m hoping it’s reasonable that the various VertexData manipulation methods operate on a convex polyhedron such that they can be executed repeatedly in any order and the last method prevails. I don’t expect that unindexed or indexed is unchanged, but the mesh vertex positions should be interpreted as (close to) identical, with the facets and winding being the same.

I’ve listed the methods I’m playing around with here.
