Georges Basile Stavracas Neto 82b037e74c clutter/paint-context: Allow assigning a ClutterFrame
This is not yet used, but next commits will need to assign a frame
to the paint context whenever painting onscreens.

Assigning a frame to the paint context is a one-way operation, and
treats multiple assignments strictly as a programming error.
