     The <function>swf_ortho2</function> function defines a two
     dimensional orthographic mapping of user coordinates onto the
     current viewport, this defaults to one to one mapping of the area
     of the Flash movie.  If a perspective transformation is desired,
     the <function>swf_perspective </function> function can be used.
