ClutterBehaviour * clutter_behaviour_opacity_new (ClutterAlpha *alpha, guint8 opacity_start, guint8 opacity_end);
Creates a new ClutterBehaviourOpacity object, driven by alpha
which controls the opacity property of every actor, making it
change in the interval between opacity_start
and opacity_end
.
