effect desired functionality and avoid infinite recursion. Since
Polygon.calculateBounds() has package-protected access, our only happily
non-deprecated alternative is to copy calculateBounds() and the code from
Polygon.getBoundingBox() into this class, explicitly avoiding a call to
bounds.getBounds(), but for now I choose to live with deprecation.
