	History:
            06/06/90 TAT/SJS add in gadget check for getting window attributes
            08/02/90 SJS clear out propagate & event masks of gadgets/regions
            09/12/90 SJS set the visibility_state of regions to be equal to
	                 their parent's visibility_state

	Summary:
            Updates the object hierarchy with recent object window
