/*!
There are 2 type of X events:<br>
a) User Actions<br>
b) Background Events<br>
<p>
User Actions are events like mouse drags and presses, key presses.
Background Events are everything else. Stuff that can't be bound to user
input.
<p>
When an XEvent comes to the application, it is sent to this class. This class
will determine what the event means, such as "A Left-Mouse-Button Drag on
this window", or "Double click with right mouse button on root window" or
"space bar pressed", or Background Event.
<p>
If the XEvent or combination of XEvents form a User Action, then the action
is dispatched to the OBBindingMapper.
<p>
If the XEvent is a Background Event, it is simply dealt with as appropriate.
