If 'current_pos' (2-float tuple) is provided, the initial moveTo will be relative to that instead being absolute. If the pen has an "arcTo" method, it is called with the original values of the elliptical arc curve commands: pen.arcTo(rx, ry, rotation, arc_large, arc_sweep, (x, y)) Otherwise, the arcs are approximated by series of cubic Bezier segments ("curveTo"), one every 90 degrees.
