    Specified by:
      `setRoundRect` in class `RoundRectangle2D`
    Parameters:

      `setRoundRect` in class `RoundRectangle2D`
    Parameters:
      `rr` - the specified `RoundRectangle2D`
    Since:
      1.2

  - ### 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.

    Note that the definition of insideness can lead to situations where points on the defining outline of the `shape` may not be considered contained in the returned `bounds` object, but only in cases where those points are also not considered contained in the original `shape`.

    If a `point` is inside the `shape` according to the `contains(point)` method, then it must be inside the returned `Rectangle2D` bounds object according to the `contains(point)` method of the `bounds`. Specifically:

    `shape.contains(p)` requires `bounds.contains(p)`

    If a `point` is not inside the `shape`, then it might still be contained in the `bounds` object:

    `bounds.contains(p)` does not imply `shape.contains(p)`

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