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