        * clutter/glx/clutter-stage-glx.c:
        * clutter/glx/clutter-backend-glx.c:
        Fix up rendering pipeline removing clutter_backend_XXX_stage_paint
        and adding clutter_backend_XXX_redraw instead. Duplicates less
        code in backends, avoids clutter_actor_paint() getting called
        before stage is set up (viewport wise) and unbreaks things like
        picking.

        Redo picking functionality a different way (via color indexing)
        as to provide more flexibility, possibly speed and more likely
        work with GL/ES (doesn't currently however - not sure why).
