*    NAME
*       led.image--Simulated LED display image.                 (V42)
*
*    SUPERCLASS
*	imageclass
*
*    DESCRIPTION
*	The led.image image class provides a simulated LED image display.
*
*    METHODS
*	OM_NEW--Create the LED image.  Passed to superclass, then OM_SET.
*
*	OM_SET--Set object attributes.  Passed to superclass first.
*
*	OM_UPDATE--Set object notification attributes.  Passed to superclass
*	    first.
*
*	IM_DRAW--Renders the images.  Overrides the superclass.
*
*	All other methods are passed to the superclass, including OM_DISPOSE.
*
*    ATTRIBUTES
*	SYSIA_DrawInfo (struct DrawInfo *) -- Contains important pen
*	    information.  This is required if IA_BGPen and IA_FGPen are
*	    not specified.
*
*	IA_FGPen (LONG) -- Pen to use to draw the lit segments.  If -1
*	    is specified then TEXTPEN is used.
*
*	IA_BGPen (LONG) -- Pen to use to draw the unlit segments or
*	    background.  If -1 is specified then BACKGROUNDPEN is used.
*
*	IA_Width (LONG) -- Width of the image.
*
*	IA_Height (LONG) -- Height of the image.
*
*	LED_Pairs (LONG) -- Number of pairs of digits.
*
*	LED_Values (WORD *) -- Array of values.  One entry per pair
*	    is required.
*
*	LED_Colon (BOOL) -- Is the colon between pairs lit or not.
*	    Defaults to FALSE.
*
*	LED_Signed (BOOL) -- Leave room for a negative sign or
*	    not.  Defaults to FALSE.
*
*	LED_Negative (BOOL) -- Is the negative sign lit or not.
*	    Defaults to FALSE.
