  17 /*!
  18   There are 2 type of X events:<br>
  19     a) User Actions<br>
  20     b) Background Events<br>
  21   <p>
  22   User Actions are events like mouse drags and presses, key presses.
  23   Background Events are everything else. Stuff that can't be bound to user
  24     input.
  25   <p>
  26   When an XEvent comes to the application, it is sent to this class. This class
  27   will determine what the event means, such as "A Left-Mouse-Button Drag on
  28   this window", or "Double click with right mouse button on root window" or
  29   "space bar pressed", or Background Event.
  30   <p>
  31   If the XEvent or combination of XEvents form a User Action, then the action
  32   is dispatched to the OBBindingMapper.
  33   <p>
  34   If the XEvent is a Background Event, it is simply dealt with as appropriate.
