wn_user_defined_color_c

	status.i4.v = wn_user_defined_color_c(red_intensity.u2.v,
					      green_intensity.u2.v,
					      blue_intensity.u2.v)

	This routine sets the drawing color using RGB values for future
	graphics calls using the "wn_xxxx" routines.  Please, note that
	most X servers only use the upper byte of the color codes.  So,
	to use traditional RGB color values with this routine, they
	should be left shifted by 8 bits.

	red_intensity	red color intensity
	green_intensity	green color intensity
	blue_intensity	blue color intensity

	This function returns status values as follows:

	OK			success
	CBS_INVARG		invalid color

	This function requires the following include files:

	cnsparam_h, cbslib_h, acnet_errors_h

	C/C++ usage:

	int	status;
	unsigned short	red_intensity = RED_INTENSITY;
	unsigned short	green_intensity = GREEN_INTENSITY;
	unsigned short	blue_intensity = BLUE_INTENSITY;

	status = wn_user_defined_color_c(red_intensity,green_intensity,
					 blue_intensity);
