// 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.
