      <summary>Mouse Tracking Mode</summary>
      <description>
        Determines the position of the magnified mouse image within the
        magnified view and how it reacts to system mouse movement. The values
        are
        • none: no mouse tracking;
        • centered: the mouse image is
        displayed at the center of the zoom region (which also represents
        the point under the system mouse) and the magnified contents are
        scrolled as the system mouse moves;
        • proportional: the position of the magnified mouse in the zoom region
        is proportionally the same as the position of the system mouse on screen;
        • push: when the magnified mouse intersects a boundary of the zoom
        region, the contents are scrolled into view.

          position of the system focus on screen

        • push: when the magnified focus intersects a boundary of the zoom region, the contents are scrolled
          into view
