wn_point_pixel_c

	status.i4.v = wn_point_pixel_c(x.i4.v, y.i4.v [,relative_pos.i4.v])

	This routine draws a point at the specified pixel
	coordinates.  The coordinates can either be absolute
	screen coordinates or relative to a graphical window
	specified by a previous call to wn_active(_c).  The
	color of the vector is determined by the most recent
	call to wn_color(_c).

	x, y		pixel coordinates of the point
	[relative_pos]	flag indicating whether the coordinates should
			be interpreted as full screen coordinates or
			if they are relative to the active window
			(TRUE -> coordinates are relative to the active window,
			 FALSE -> coordinates are absolute screen coordinates
				  (default))

	This function returns ACNET status values as follows:

	OK			success
	CBS_NOSETUP		an active window has not been established
	CBS_MEMFAIL		failed in allocating dynamic memory

	This function requires the following include files:

	cbslib_h, acnet_errors_h
