Polyhedron does not manipulation of low-level functions directly. To get
that functionality you need to use the interface provided by
Polyhedron::delegate [1]. It feels a little awkward at first, but
Incremental_builder should give a good usage example [2]. Technically,
incremental builder should already able to do what you want with
RELATIVE_INDEXING.
