### getBounds2D

    public Rectangle2D getBounds2D()

  Returns a high precision and more accurate bounding box of the `Shape` than the `getBounds` method. Note that there is no guarantee that the returned `Rectangle2D` is the smallest bounding box that encloses the `Shape`, only that the `Shape` lies entirely within the indicated `Rectangle2D`. The bounding box returned by this method is usually tighter than that returned by the `getBounds` method and never fails due to overflow problems since the return value can be an instance of the `Rectangle2D` that uses double precision values to store the dimensions.

  Specified by:
    `getBounds2D` in interface `Shape`
  Returns:
    an instance of `Rectangle2D` that is a high-precision bounding box of the `Shape`.
  Since:
    1.2
