41  * The JGoodies Windows Look&Feel implementation for
42  * arrow buttons used in scrollbars and comboboxes.
43  * <p>
44  * It differs from <code>BasicArrowButton</code> in that the preferred size
45  * is always a square.
46  * It differs from <code>WindowsScrollBarUI.WindowsArrowButton</code>
47  * in that the triangle is black and positioned correctly.
