.SH DESCRIPTION
These three procedures are event dispatchers. 
.PP
\fBEZ_EventMainLoop\fR is the main event loop. It is an infinite
loop that wait for user interactions. When an event arrives, it
calls the responsible event handlers to handle the event. 
.PP
\fBEZ_ServiceEvents\fR checks the event queue for
outstanding events.  If there are any, it dispatches 
all of them to the responsible event handlers and then returns.
.PP
\fBEZ_WaitAndServiceNextEvent\fR checks the event queue. It waits
for the next event to arrive if the event queue is empty. It
then processes the first outstanding event and returns.
