Comment:

 The patch is in principle ready, but while we are at it - do we want to
 make custom `_repr_` for such morphisms? If yes, how should they be
 different from the standard?

 Also, the speed is far from spectacular, but it is not easy to make it
 better until simple polyhedra work faster - currently most time is spend
 on constructing them for intersection purposes and I tried hard not to
 intersect more cones than necessary.
