lex_draw_display_c

	status.i4.v = lex_draw_display_c(file_name.i1a.r, image_number.i4.v,
					 display_type.i4.v [,resize_type.i4.v])

	This routine is used to display saved Lex Draw images on the color
	graphics displays.  Images can be edited and saved files by using
	the interactive graphics image editor (Lex Draw), currently on
	page D28.  This routine can be called by both PA's and SA's.  
	Programs which call 'lex_draw_display_c' should normally call
	wn_screen_init(_c) or LXRST at initalization to reset the
	graphics screen parameters and to define the image title.
	(Note: This routine should be used in place of lximag.)

	file_name	graphics image filename (LEXT_IMAGE_NAMLEN characters)
	image_number	image number (>= 1)
	display_type	type of display requested
			(LEXT_DISPLAY -> display graphics image with erase
					 (Image number "image_number" in the
					 graphics file specified by
					 "file_name" is displayed.),
			 LEXT_DISPLAY_NOERASE -> display graphics image
						 without erase,
			 LEXT_DISPLAY_BLINK -> display blinking image with
					       erase,
			 LEXT_DISPLAY_NOERASE_BLINK -> display blinking image
						       without erase)
	[resize_type]	background window resize mode
			(LEXT_RESIZE_TO_FIT -> allow background window resize
					       to fit the image (default),
			 LEXT_RESIZE_LARGER_ONLY -> allow background window
						    resize (larger only),
			 LEXT_NO_RESIZE -> don't allow background window resize)

	This function returns ACNET status values as follows:

	OK			success
	CLIB_INVARG		invalid display type passed
	CLIB_INVID		invalid image number passed
	FSHARE_xxx		image file access error

	This function requires the following include files:

	clib_h, acnet_errors_h

	C/C++ usage:

	static const char	file_name[LEXT_IMAGE_NAMLEN+1] = "XXXXXXXX";
	int	status;
	int	image_number = 1;
	int	display_type = LEXT_DISPLAY;
	int	resize_type = LEXT_RESIZE_TO_FIT;

	status = lex_draw_display_c(file_name,image_number,display_type,
				    resize_type);
