Georges Basile Stavracas Neto 4898408404 clutter/effect: Add paint nodes to all paint vfuncs
In the purely paint node based rendering future, ClutterEffects
simply add more paint nodes to the tree when painting the actor.

This is the leap to achieve that future.

Add paint nodes to pre_paint, paint, and post_paint, and move the
ClutterEffectNode creation to _clutter_effect_paint().
