You cannot assume that the parent is any particular kind of object, only
that there is one.

Also, I think this does not belong in transform because:
- Transform does not alter the format while running. Motion needs to.
- Transform is a top contender for ASM optimizations, that would break.
- Transform only rotates pictures. Motion should rotate pictures _and_
subs.
