    wmgeneral was taken from wmppp.

    It has a lot of routines which most of the wm* programs use.

    CHANGES:
    ---
    11/08/2002 (Brad Jorsch, anomie@users.sourceforge.net)
        * Moved all the rc-file related stuff to rcfile.[ch]

    28/08/2001 (Brad Jorsch, anomie@users.sourceforge.net)
        * Added EnableMouseRegion and DisableMouseRegion
        * Got annoyed with the 81-character lines. Fixed it. If you don't like
          it, find a different copy of wmgeneral.c ;)
        * GraphicsExpose events are enabled here.
        * GetXPM is exported. It optionally takes an XpmColorSymbol array.
        * GetColor is exported.

    30/09/2000 (Brad Jorsch, anomie@users.sourceforge.net)
    * You know, wmgen.mask sounds like a much nicer place to store the
      mask... why don't we do that?

    21/09/1999 (Brad Jorsch, anomie@users.sourceforge.net)
        * Changed openXwindow to use only the filename, sans path,
          as the name and class properties of the app.

    14/09/1998 (Dave Clark, clarkd@skyia.com)
        * Updated createXBMfromXPM routine
        * Now supports >256 colors
    11/09/1998 (Martijn Pieterse, pieterse@xs4all.nl)
        * Removed a bug from parse_rcfile. You could
          not use "start" in a command if a label was
          also start.
        * Changed the needed geometry string.
          We don't use window size, and don't support
          negative positions.
    03/09/1998 (Martijn Pieterse, pieterse@xs4all.nl)
        * Added parse_rcfile2
    02/09/1998 (Martijn Pieterse, pieterse@xs4all.nl)
        * Added -geometry support (untested)
    28/08/1998 (Martijn Pieterse, pieterse@xs4all.nl)
        * Added createXBMfromXPM routine
        * Saves a lot of work with changing xpm's.
    02/05/1998 (Martijn Pieterse, pieterse@xs4all.nl)
        * changed the read_rc_file to parse_rcfile, as suggested by Marcelo E. Magallon
        * debugged the parse_rc file.
    30/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
        * Ripped similar code from all the wm* programs,
          and put them in a single file.
