windowManager: add animations for fullscreen and unfullscreen
We use the newly introduced feature from Mutter to hook up our own fullscreen and unfullscreen animations. To give the illusion of a transition as smooth as possible, we create a snapshot of the current contents of the actor before its state is changed, and crossfade between the two states while the size changes. https://bugzilla.gnome.org/show_bug.cgi?id=707248
