// -=- WMNotifier.h

// The WMNotifier is used to get callbacks indicating changes in the state
// of the system, for instance in the size/format/palette of the display.
// The WMNotifier contains a Win32 window, which receives notifications of
// system events and stores them. Whenever processEvent is called, any
// incoming events are processed and the appropriate notifier called.
