   1 /* MinimizeToTray
   2  *
   3  * A couple of routines to show how to make it produce a custom caption
   4  * animation to make it look like we are minimizing to and maximizing
   5  * from the system tray
   6  *
   7  * These routines are public domain, but it would be nice if you dropped
   8  * me a line if you use them!
   9  *
  10  * 1.0 29.06.2000 Initial version
  11  * 1.1 01.07.2000 The window retains it's place in the Z-order of windows
  12  *     when minimized/hidden. This means that when restored/shown, it doesn't
  13  *     always appear as the foreground window unless we call SetForegroundWindow
  14  *
