Some geometry management bugs fixed (and some others added -- will fix them
today). Next I will make the handle box use a transient window. It should be done that way, according to the ICCCM. We have to talk to the KDE guys to use their window manager protocol to let the WM know that we don't want decoration on our window. This has to be hacked into other WMs, too. - Federico
