* 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.
