//! Handles X events
/*!
  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.
