Emmanuele Bassi ba8d682c09 actor: Deprecate [sg]et_geometry() 
These methods are short-hands for accessing the position and size,
which are already shorthands for accessing the various dimensional
and positional attributes. Plus, they use ClutterGeometry, which is a
fairly bad data type for a rectangle.
