 *   Windows 95 style interface tweaks.
 *   Copyright (c) 1997 Dave Cuthbert.
 *
 *   FIXME:  This file is, unfortunately, aptly named:  the method of
 *   displaying Win95 style windows is a tweak.  Lots of stuff does not yet
 *   work -- and probably never will unless some of this code is
 *   incorporated into the mainstream Wine code.
 *
 *   DEVELOPERS, PLEASE NOTE:  Before delving into the mainstream code and
 *   altering it, consider how your changes will affect the Win3.1 interface
 *   (which has taken a major effort to create!).  After you make any sort of
 *   non-trivial change, *test* the Wine code running in Win3.1 mode!  The
 *   object here is to make it so that the person who tests the latest version
 *   of Wine without adding the tweaks into wine.conf notices nothing out of
 *   the ordinary.
 *
 *   Revision history
 *        03-Jul-1997 Dave Cuthbert (dacut@ece.cmu.edu)
 *             Original implementation.
 *
 *        05-Aug-1998 Eric Kohl (ekohl@abo.rhein-zeitung.de)
 *             Removed some unused code.
