	---Purpose: Creates a context table for line primitives
	--	    defined with the following default values:

	--	    Colour	: NOC_YELLOW

	---Level: Public
	---Purpose: Creates a context table for line primitives
	--	    defined with the specified values.
	--  Warning: <AWidth> is the "linewidth scale factor".
	--	    The nominal line width is 1 pixel. The width of
	--	    the line is determined by applying the linewidth scale
	--	    factor to this nominal line width.
	--	    The supported linewidths vary by 1-pixel units.
