Event handling consists of getting events and then distributing them to
the event handlers. In PLWM this is handled by the module
event and its classes EventFetcher and
EventDispatcher. If the event loop in the WindowManager
is the heart driving the event blood stream, EventFetcher is the
lungs providing fresh events (the oxygene) and EventDispatcher is
the arteries delivering the events to all the working parts of the
window manager body.
