Implements a generic ClutterActorClone that doesn't need fbos. Many use cases for clonning an actor don't require running a shader on the resulting clone image and so requiring FBOs in these cases is overkill and in-efficient as it requires kicking and synchronizing a render for each clone. This approach basically just uses the paint function of another actor to implement the painting for the clone actor with some fiddling of the model- view matrix to scale according to the different allocation box sizes of each of the actors. A simple unit test called test-actors2 was added for testing.

Allow passing the pick mode to get_actor_at_pos() Bug 1513 - Allow passing in ClutterPickMode to clutter_stage_get_actor_at_pos() At the moment, clutter_stage_get_actor_at_pos() uses CLUTTER_PICK_ALL internally to find an actor. It would be useful to allow passing in ClutterPickMode to clutter_stage_get_actor_at_pos(), so that the caller can specify CLUTTER_PICK_REACTIVE as a criteria.

clutter_actor_hide (real_hand);
Implements a generic ClutterActorClone that doesn't need fbos. Many use cases for clonning an actor don't require running a shader on the resulting clone image and so requiring FBOs in these cases is overkill and in-efficient as it requires kicking and synchronizing a render for each clone. This approach basically just uses the paint function of another actor to implement the painting for the clone actor with some fiddling of the model- view matrix to scale according to the different allocation box sizes of each of the actors. A simple unit test called test-actors2 was added for testing.

Rename ActorClone to Clone/2 Step two: rename the object and its methods. While we're at it, adhere more strictly to the coding style practises; rename :clone-source to :source; add a setter method for the :source property; take a reference on the source actor to avoid it disappearing while we're still accessing it.

Improves the unit test to verify more awkward scaling and some corresponding fixes This simplifies the mucking about with the model-view matrix that was previously done which improves its efficiency when scaling is necessary. Notably: There should now be no performance advantage to using ClutterCloneTexture as a special case clone actor since this method is just as efficient. The unit test was renamed to test-actor-clone.
