  16     ---
  17     11/08/2002 (Brad Jorsch, anomie@users.sourceforge.net)
  18         * Moved all the rc-file related stuff to rcfile.[ch]
  19
  20     28/08/2001 (Brad Jorsch, anomie@users.sourceforge.net)
  21         * Added EnableMouseRegion and DisableMouseRegion
  22         * Got annoyed with the 81-character lines. Fixed it. If you don't like
  23           it, find a different copy of wmgeneral.c ;)
  24         * GraphicsExpose events are enabled here.
  25         * GetXPM is exported. It optionally takes an XpmColorSymbol array.
  26         * GetColor is exported.
  27
  28     30/09/2000 (Brad Jorsch, anomie@users.sourceforge.net)
  29     * You know, wmgen.mask sounds like a much nicer place to store the
  30       mask... why don't we do that?
  31
  32     21/09/1999 (Brad Jorsch, anomie@users.sourceforge.net)
  33         * Changed openXwindow to use only the filename, sans path,
  34           as the name and class properties of the app.
  35
  36     14/09/1998 (Dave Clark, clarkd@skyia.com)
  37         * Updated createXBMfromXPM routine
  38         * Now supports >256 colors
  39     11/09/1998 (Martijn Pieterse, pieterse@xs4all.nl)
  40         * Removed a bug from parse_rcfile. You could
  41           not use "start" in a command if a label was
  42           also start.
  43         * Changed the needed geometry string.
  44           We don't use window size, and don't support
  45           negative positions.
  46     03/09/1998 (Martijn Pieterse, pieterse@xs4all.nl)
  47         * Added parse_rcfile2
  48     02/09/1998 (Martijn Pieterse, pieterse@xs4all.nl)
  49         * Added -geometry support (untested)
  50     28/08/1998 (Martijn Pieterse, pieterse@xs4all.nl)
  51         * Added createXBMfromXPM routine
  52         * Saves a lot of work with changing xpm's.
  53     02/05/1998 (Martijn Pieterse, pieterse@xs4all.nl)
  54         * changed the read_rc_file to parse_rcfile, as suggested by Marcelo E. Magallon
  55         * debugged the parse_rc file.
  56     30/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
  57         * Ripped similar code from all the wm* programs,
  58           and put them in a single file.
