Comment:
Making it work properly with quotient lattices is a noble goal, of course.
Another question is where to put the method to restrict line bundles from
the ambient to the orbit closure. Because of the quotient lattice it is
not literally pull-back by a toric morphism. I tend to think that
`ToricOrbitClosure` should derive from `ToricVariety` and add a
`restrict_divisor()` method.
Though as far as this ticket is concerned, I think we all agree that there
should be a `.orbit_closure(cone)` method for toric varieties that returns
a toric variety. So maybe we should merge this ticket before improving the
presentation of the resulting toric variety.
