Carlos R. Mafra 21625f40b5 Initial dockapps git repo 
I tried to get the latest versions from dockapps.org, but I haven't
tested any of them.

More dockapps will be added as time permits.

/*
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)
* This is based on wmgeneral-x11.c (formerly wmgeneral.c), it
implements a subset of the interface using Gtk+ 2.0
