    	---Purpose: Draws each axis of a trihedron displayed in the
    	-- presentation aPresentation and with lines shown by
    	-- the values of aLineAspect. Each axis is defined by:
    	-- -   the first and last points aPfirst and aPlast
    	-- -   the direction aDir and
    	-- -   the value aVal which provides a value for length.
    	--  The value for length is provided so that the trihedron
    	-- can vary in length relative to the scale of shape display.
    	-- Each axis will be identified as X, Y, or Z by the text aText.
