This orientation is doable.  We can add it as a new orientation.  Let's call
it opposing-landscape.

Valentin, can you add this to the tracker as a feature request?

My first thought was that this would have to wait until 2.14, because of the
syntax change.  However, my second thought is that we can do it now, because
it's *new* syntax, not changed syntax -- no convert-ly rule is necessary.

Release meister Graham, am I correct in this assessment?
