Unfortunately, there's not a way (that I know of) to access the vertices in a
native mesh.

So I cut/pasted the vertices into an array, and put a loop into the mesh2 to
cycle through the array.

To be able to easily reuse the mesh2 definition, I set a flag to either use the
original vertices, or run a macro to apply the Bezier distortion.

#macro MakeMesh (Distorted)

 mesh2 {
  vertex_vectors {
  42,
  #for (V, 0, 41)
   #if (Distorted)
    DistortedVertex (MeshVertices [V]),
   #else
    MeshVertices [V],
   #end
  #end
  }
.. . . etc.

I know it would be great if we could just easily include any mesh, or run it
through a macro, but at present, I don't think that there's any way to do that.

I am pretty happy that it just required some "minor" modification to the formula
generating code, and this wasn't a major multiple-month project.

Anyway, it shows proof of concept.     :)
