	status.i4.v = window_set_clip_c(window_id.i2.v, clip.i4.v)

	This routine enables or disables clipping in the window indicated
	by "window_id".

	clip		clipping flag
			(WMNGR_CLIP_IT -> disable I/O to the window border
					  (default),
			 WMNGR_NO_CLIP -> enable I/O to the window border,

					     clipping state)

	CBS_INVARG		invalid window ID was specified
	CBS_NO_WINDOW		requested window does not exist
	CBS_INVTYP		window has no border and cannot be clipped
	CBS_MEMFAIL		dynamic memory allocation failure
