Yes we could, but I'd rather not. Why do we need it? I'd prefer if
DOLFIN did not know anything about dofs, other than how to reorder
them.

I see two options:

 1. Reorder the dofs computed by FFC, not knowing why and how they
    are numbered.

 2. Compute a different mapping in FFC.

I can be convinced otherwise of course, but I don't understand why
this is needed.
