  15     CHANGES:
  16     ---
  17     15/08/2002 (Brad Jorsch, anomie@users.sourceforge.net)
  18         * Updated createXBMfromXPM to handle the case where the XBM is to be
  19           wider than the XPM, or the XBM width is not a multiple of 8.
  20         * Pulled createXBMfromXPM into its own file, because it's the same in
  21           both -gtk and -x11.
  22
  23     11/08/2002 (Brad Jorsch, anomie@users.sourceforge.net)
  24         * Removed the rc-file and mouse region stuff to their own files.
  25         * Renamed this file to "wmgeneral-x11.c"
  26         * Renamed a few of the functions
  27
  28     28/08/2001 (Brad Jorsch, anomie@users.sourceforge.net)
  29         * Added EnableMouseRegion and DisableMouseRegion
  30         * Got annoyed with the 81-character lines. Fixed it. If you don't like
  31           it, find a different copy of wmgeneral.c ;)
  32         * GraphicsExpose events are enabled here.
  33         * GetXPM is exported. It optionally takes an XpmColorSymbol array.
  34         * GetColor is exported.
  35
  36     30/09/2000 (Brad Jorsch, anomie@users.sourceforge.net)
  37     * You know, wmgen.mask sounds like a much nicer place to store the
  38       mask... why don't we do that?
  39
  40     21/09/1999 (Brad Jorsch, anomie@users.sourceforge.net)
  41         * Changed openXwindow to use only the filename, sans path,
  42           as the name and class properties of the app.
  43
  44     14/09/1998 (Dave Clark, clarkd@skyia.com)
  45         * Updated createXBMfromXPM routine
  46         * Now supports >256 colors
  47     11/09/1998 (Martijn Pieterse, pieterse@xs4all.nl)
  48         * Removed a bug from parse_rcfile. You could
  49           not use "start" in a command if a label was
  50           also start.
  51         * Changed the needed geometry string.
  52           We don't use window size, and don't support
  53           negative positions.
  54     03/09/1998 (Martijn Pieterse, pieterse@xs4all.nl)
  55         * Added parse_rcfile2
  56     02/09/1998 (Martijn Pieterse, pieterse@xs4all.nl)
  57         * Added -geometry support (untested)
  58     28/08/1998 (Martijn Pieterse, pieterse@xs4all.nl)
  59         * Added createXBMfromXPM routine
  60         * Saves a lot of work with changing xpm's.
  61     02/05/1998 (Martijn Pieterse, pieterse@xs4all.nl)
  62         * changed the read_rc_file to parse_rcfile, as suggested by Marcelo E. Magallon
  63         * debugged the parse_rc file.
  64     30/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
  65         * Ripped similar code from all the wm* programs,
  66           and put them in a single file.
