Reviewing merge request #1398: Support for nesting GtkClutterActor

Right now, the GtkBin associated with a GtkClutterActor can only be the top-level container of a GTK+ widget stack. This is a limitation when animation is needed for a GtkWidget and one of its children at the same time.
With this feature, any widget could be wrapped by a GtkClutterActor, while keeping advantage of the GTK+ laying-out.

The proposed changes aim to provide support for this. Basically it allows the GtkBin of the GtkClutterActor, to be contained inside any GtkContainer, not just GtkClutterEmbed.
When a GtkClutterActor is added to a GtkContainer other than the GtkClutterEmbed, this actor is considered "nested", and will be placed following GTK+ layout rules.

A demo is included (examples/gtk-clutter-actor-nested.c) that shows the feature in action: A GtkVBox wrapped by a GtkClutterActor, and GtkButtons inside. The middle button is wrapped by another GtkClutterActor. Both actors are being rotated simultaneously on opposite directions. The key of the demo is seeing how the GtkClutterActor wrapping the button, is laid-out by GTK+ automatically.

Testing and feedback is very appreciated.

cheers

At the moment i'm busy with general csw regresion fixing. Emmanuele Bassi and Davyd Madeley are doing clutter-gtk work, you should talk to them instead.
