             This is a generalization of MetaPostArrow to 3d (let us not look closer at what this really means).  Note that the mandatory normal means that this function is not a §ArrowHead3D until this argument has been bound. 
            Please refer to the discussion about 3d arrowheads in ..Shapes..Graphics3D / arrowheads for ways to avoid the need to specify the surface normal.
