+/**
+ * Based on AquaInternalFrameManager
+ *
+ * DesktopManager implementation for Aqua
+ *
+ * Mac is more like Windows than it's like Motif/Basic
+ *
+ *    From WindowsDesktopManager:
+ *
+ * This class implements a DesktopManager which more closely follows
+ * the MDI model than the DefaultDesktopManager.  Unlike the
+ * DefaultDesktopManager policy, MDI requires that the selected
+ * and activated child frames are the same, and that that frame
+ * always be the top-most window.
+ * <p>
+ * The maximized state is managed by the DesktopManager with MDI,
+ * instead of just being a property of the individual child frame.
+ * This means that if the currently selected window is maximized
+ * and another window is selected, that new window will be maximized.
+ *
+ * @see com.sun.java.swing.plaf.windows.WindowsDesktopManager
