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.
