* Description:  Multiple status windows interface.
*
****************************************************************************/


/*
 *  This code will create multiple status windows for a windows app,
 *  like used in vi and wvideo.  Use as follows :
 *
 *  StatusWndInit -          called once only to set up class.  Supply a
 *                           hook function and the amount of extra data.
 *
 *  StatusWndStart -         called once per status window. Returns a status
 *                           window handle.
 *
 *  StatusWndCreate -        call when you wish to actually create the status
 *                           window, passing a status window handle, parent,
 *                           location, and lpvParam.
 *
 *  StatusWndDrawLine -      call when you wish to draw a new line.  Pass in
 *                           the display context, a font handle, a string
 *                           (which may contain STATUS_ESC_CHAR + STATUS_..
 *                           characters), and a DrawText flags setting.
 *                           If the flags are set to -1, then the string
 *                           will be parsed for escape sequences.
 *
 *  StatusWndSetSeparators - call to set up multiple blocks.  Pass in the
 *                           number of blocks, and an array describing
 *                           each block.
 *
 *  StatusWndDestroy -       call when you are finished with a status window
 *
 *  StatusWndFini -          call when you are finished with all status
 *                           windows. Make sure all status windows have been
 *                           destroyed!
