    paint-volumes: avoid trashing is_static state
    
    In _clutter_paint_volume_set_from_volume we were using memcpy to simply
    copy everything from one volume to another, but that meant we were
    trashing the is_static flag which determines if the destination
    paint-volume was slice allocated or not.
