Set the IN_PAINT private flag

Browse Source 
When calling clutter_actor_paint() we should be setting the
CLUTTER_ACTOR_IN_PAINT private flag. This allows signalling
to each Actor subclass that we are effectively in the middle
of a paint sequence. Actor subclasses can check for this
private flag and act based on its presence - for instance to
avoid recursion, or to detect performance degradation cases.
