      public Region intersection(Region r)
      Returns a Region representing the intersection of this Region with the given Region. If the two Regions do not intersect, the result is an empty Region.
      Parameters:
      r - the region for which to calculate an intersection (or overlap)
      Returns:
      a Region representing the intersection (overlap) of the two Regions. If the two Regions have no common area, then the width and/or height of the returned Region will be 0. null is never returned.
