* clutter/clutter-actor.c:
        * clutter/clutter-actor.h:
        Add new set_width/height API calls.
        Tweak scaling by reseting matrix.
        Make set_opactiy() take parent opacity into account.
        Fix clipping.

        * clutter/clutter-alpha.c:
        Add more sine functionality.

        * clutter/clutter-behaviour-opacity.c:
        Dont make a copy of all applied actors but use a foreach()

        Give correct limits to propertys.
        Tweak gravity a little more.
        Update docs.
:
        * clutter/clutter-behaviour.c: (clutter_behaviour_remove):
        Minor warning text change.

        * clutter/clutter-feature.c: (clutter_feature_wait_for_vblank):
        Minor dri ioctl tweak.

        * clutter/clutter-label.c:
