wn_set_cursor_position(_c)

	status.i4.v = wn_set_cursor_position_c(window_id.i4.v, x.r8.v, y.r8.v)

	This routine moves the graphics cursor to the coordinates
	and window specified.  The specified window becomes the
	presently active window for graphical operations using
	"wn_xxxx" routines.

	window_id	window ID returned from call to wn_view(_c)
			(use WN_BACKGROUND for background window)
	x, y		world coordinates to position cursor  (The value
			WN_CENTER_IT can be used for one or both coordinates
			to center the cursor in the requested window.)

	This function returns ACNET status values as follows:

	OK			success
	CBS_INVARG		invalid ID value
	CBS_INVID		this window doesn't exist
	CBS_NOSETUP		scaling for this window hasn't been established
	CBS_RANGE		coordinate is not within the limits of
				the requested window or it is invalid for
				the scaling of the requested window

	This function requires the following include files:

	cbslib_h, acnet_errors_h
