  Meshes are internally stored in a data structure which resembles a lot
how information is stored in the mesh2 format.

  In theory it could be possible to allow the user to modify the vertex
points of an existing mesh. However, it probably requires some extra
work, as modifying the vertices invalidates the octree structure of the
mesh and has to be calculated again.
