Emmanuele Bassi 391f1d8dd4 constraint: Add the ability to update the preferred size
Constraints can only update an existing allocation, which means they
live only halfway through the layout management system used by Clutter;
this limitation makes it impossible, for instance, to query the
preferred size of an actor, if the actor is only using constraints to
manage its own size.
