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.

high-precision bounding box of the Shape.Shape.getBounds()
