Best viewed with vim5, using ts=4
wmgeneral was taken from wmppp.
It has a lot of routines which most of the wm* programs use.

CHANGES:
---
15/08/2002 (Brad Jorsch, anomie@users.sourceforge.net)
* Pulled createXBMfromXPM into its own file, because it's the same in
both -gtk and -x11.
11/08/2002 (Brad Jorsch, anomie@users.sourceforge.net)
* Removed the rc-file and mouse region stuff to their own files.
* Renamed this file to "wmgeneral-x11.c"
* Renamed a few of the functions
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.
