status.i4.v = wn_vector_width(width.i4.r)

	status.i4.v = wn_vector_width_c(width.i4.v)

	This routine sets the vector width for vectors drawn by the "wn_xxx"
	graphics routines.

	width		width of vectors in pixels
			(If a value of CLIB_DEFAULT_ARG is passed for this
			argument, the present width will simply be returned
			to the caller.)

	This function returns status values as follows:

	CBS_INVARG		invalid width
	otherwise		previous vector width setting

	This function requires the following include files:

	clib_h, cbslib_h, acnet_errors_h

	Related functions:

	wn_vector(_c), wn_polygon_c, wn_vector_grain(_c), wn_wide_vector_c,

	C/C++ usage:

	int	status;
	int	width = 1;

	status = wn_vector_width_c(width);
