/**
  A class to create, modify and delete menus that appear on Mac OS X in the menu bar at the top of the screen.
 
  On other than Mac OS X platforms, Fl_Sys_Menu_Bar is a synonym of class Fl_Menu_Bar.
 \n To use this class, just replace Fl_Menu_Bar by Fl_Sys_Menu_Bar, and, on the Mac platform,
 a system menu at the top of the screen will be available. This menu will match an array
 of Fl_Menu_Item's exactly as with standard FLTK menus.
  
  Changes to the menu state are immediately visible in the menubar when they are made
  using member functions of the Fl_Sys_Menu_Bar class. Other changes (e.g., by a call to
  Fl_Menu_Item::set()) should be followed by a call to Fl_Sys_Menu_Bar::update() to be
  visible in the menubar across all platforms.
  
  A few FLTK features are not supported by the Mac System menu:

  \li no symbolic labels
  \li no embossed labels
  \li no font sizes
 
  You can configure a callback for the 'About' menu item to invoke your own code with fl_mac_set_about().
