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.

Remove CloneTexture from the API ClutterClone supercedes ClutterCloneTexture, since it can clone every kind of actor -- including composite ones. This is another "brain surgery with a shotgun" kind of commit: it removes CloneTexture and updates every test case using CloneTexture to ClutterClone. The API fallout is minimal, luckily for us.

[clone] Allow cloning unparented actors If the source of a ClutterClone does not have a parent actor the clone will be unable to paint it because it's missing an allocation. A simple way to fix it is to make the ClutterClone act like a "foster parent": when it is allocated it will check if the source actor has a parent and if not it will allocate the source with its preferred size.

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.

* Creates a new #ClutterActor which clones @source/
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.
