  13     wmgeneral was taken from wmppp.

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

  23     ---
  24     11/08/2002 (Brad Jorsch, anomie@users.sourceforge.net)
  25         * Moved all the mouse region related stuff to mouse_regions.[ch]
  26
  27     28/08/2001 (Brad Jorsch, anomie@users.sourceforge.net)
  28         * Added EnableMouseRegion and DisableMouseRegion
  29         * Got annoyed with the 81-character lines. Fixed it. If you don't like
  30           it, find a different copy of wmgeneral.c ;)
  31         * GraphicsExpose events are enabled here.
  32         * GetXPM is exported. It optionally takes an XpmColorSymbol array.
  33         * GetColor is exported.
  34
  35     30/09/2000 (Brad Jorsch, anomie@users.sourceforge.net)
  36     * You know, wmgen.mask sounds like a much nicer place to store the
  37       mask... why don't we do that?
  38
  39     21/09/1999 (Brad Jorsch, anomie@users.sourceforge.net)
  40         * Changed openXwindow to use only the filename, sans path,
  41           as the name and class properties of the app.
  42
  43     14/09/1998 (Dave Clark, clarkd@skyia.com)
  44         * Updated createXBMfromXPM routine
  45         * Now supports >256 colors
  46     11/09/1998 (Martijn Pieterse, pieterse@xs4all.nl)
  47         * Removed a bug from parse_rcfile. You could
  48           not use "start" in a command if a label was
  49           also start.
  50         * Changed the needed geometry string.
  51           We don't use window size, and don't support
  52           negative positions.
  53     03/09/1998 (Martijn Pieterse, pieterse@xs4all.nl)
  54         * Added parse_rcfile2
  55     02/09/1998 (Martijn Pieterse, pieterse@xs4all.nl)
  56         * Added -geometry support (untested)
  57     28/08/1998 (Martijn Pieterse, pieterse@xs4all.nl)
  58         * Added createXBMfromXPM routine
  59         * Saves a lot of work with changing xpm's.
  60     02/05/1998 (Martijn Pieterse, pieterse@xs4all.nl)
  61         * changed the read_rc_file to parse_rcfile, as suggested by Marcelo E. Magallon
  62         * debugged the parse_rc file.
  63     30/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
  64         * Ripped similar code from all the wm* programs,
  65           and put them in a single file.
