status.i4.v = wn_view_pixel_c(window_id.i4.r, x_min_pixel.i4.v,
				      y_min_pixel.i4.v, x_max_pixel.i4.v,

	This routine creates and sets the screen limits (virtual coordinates)
	for a graphics window based on pixel coordinates.

	window_id	returned window ID
	x_min_pixel	X pixel coordinate of left border of window
	y_min_pixel	Y pixel coordinate of the bottom of the window
	x_max_pixel	X pixel coordinate of right border of window
	y_max_pixel	Y pixel coordinate of the top of the window

	This function returns ACNET status values as follows:

	OK			success
	CBS_INVARG		invalid coordinates specified
	CBS_MEMFAIL		failed in allocating dynamic memory

	This function requires the following include files:

	cbslib_h, acnet_errors_h

	Related functions:

	wn_view(_c), wn_view_construct_c, wn_view_text_format_c, wn_world(_c),
	wn_active(_c), intro_graphics_windows

	C/C++ usage:

	int	status;
	int	window_id;
	int	x_min_pixel = 64;
	int	y_min_pixel = 51;
	int	x_max_pixel = 576;
	int	y_max_pixel = 461;

	status = wn_view_pixel_c(&window_id,x_min_pixel,y_min_pixel,
