    x11: adjust size to minimal size when realizing
    
    If you execute the following sequence :
    
    stage = clutter_stage_new ();
    clutter_actor_set_size (stage, 1280, 800);
    clutter_actor_realize (stage);
    
    Then you end up creating an onscreen buffer of size 1280x800 but
    ClutterStageX11 storing the stage size at 640x480.
    
    This patch resync the 2 implementation by using the ClutterStage's
    size in both classes when realizing.
