/**
* 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
