If you can, it's probably best to implement the allocate function of the
actor, rather than hooking into notify of width and height. Changing
texture sizes (if you are using ClutterTextre actor) should certainly be
done during allocation with clutter_actor_allocate, and this will avoid
causing a allocation cycle warning.

Adding and removing actors from the stage will cause a re-layout because
any new children will need to be allocated for the first time and the
parent actors of children removed need to be updated.

One solution may be to just have the children hidden until they are
needed.
