If set to `true`, the subelement offset (the distance from x0 y0 to the most top-left point) will be reset to x0 y0.

    element.attr({
      path: {
        // The path bbox for `d="M 10 10 20 20"` is x10 y10 w10 h10.
        d: 'M 10 10 20 20',
        // The path bbox will be changed to x0 y0 w10 h10.
        // This has same effect as passing path with `d="M 0 0 10 10"`
        resetOffset: true
      }
    });
