Merge branch 'generic-actor-clone'
* generic-actor-clone: Remove CloneTexture from the API [tests] Clean up the Clone interactive test Rename ActorClone to Clone/2 Rename ActorClone to Clone/1 Improves the unit test to verify more awkward scaling and some corresponding fixes Implements a generic ClutterActorClone that doesn't need fbos.
