  12.    This program opens up a window with three gadgets in it, using
  13.    egsgadbox.library.  Each gadget prints its own message to the
  14.    console.
  15.  
  16.    This demonstrates how to use CreateHorizBox() to get multiple
  17.    gadgets, and react to different action gadget messages.
