  01/14/2005    1.00    initial draft
  02/23/2005    1.01    added callbacks, implemented changes as discussed
  02/08/2006    1.02    added call to set foreground, sync update with confirmation
  05/29/2006    1.03    Added device family feature
  12/03/2007    3.00    Added support for color devices and partial event notifications (arrival and removal)
  10/03/2008    3.01    Added more event notifications
  10/27/2008    3.01    Deprecated enumeration and index-based open; Applets should use lgLcdOpenByType() (and
                        possibly notifications)
