    stage-window: Add get_hw_geometry() method
    
    This is an alternative to _clutter_stage_window_get_geometry(), that
    will return the geometry as seen by the stage. get_hw_geometry() will
    return the geometry as seen by the lower layers (eg. on rotated outputs
    we still need to allocate primary planes that fit the crcts).
