{ Message handler for the hidden shell notification window. Most messages
  use WM_SYSTEM_TRAY_MESSAGE as the Message ID, with WParam as the ID of the
  shell notify icon data. LParam is a message ID for the actual message, e.g.,
  WM_MOUSEMOVE. Another important message is WM_ENDSESSION, telling the shell
  notify icon to delete itself, so Windows can shut down.

  Send the usual events for the mouse messages. Also interpolate the OnClick
  event when the user clicks the left button, and popup the menu, if there is
  one, for right click events. }
