Georges Basile Stavracas Neto 9e011958d4 clutter/stage: Add new before_paint signal hook
It'll allow subclasses to get notified of the before-paint
signal without having to connect to it. This will allow
MetaStage to have proper watches being fired there without
the cost of the signal handling machinery.
