    pointerA11yTimeout: Draw a clean circle if the pie is finished
    
    If the circle is complete and the pie timeout finished, we don't need
    the lines to the center point indicating the ends of the pie anymore.
    We just draw a clean circle instead, which allows for a zoom-out and
    fade animation of the circle when we're done.
