Good idea! However, I don't have xfwm4 installed ATM and I fear some loss of 
KDE-ness functionality.

I dug up the KDE compliance matrix for the standard and found out that the wm 
relies on individual windows identifying themselves as dock or panel windows 
with a "_NET_WM_STRUT_PARTIAL" property or a "_NET_WM_WINDOW_TYPE" of "DOCK" 
or similar (see 
http://freedesktop.org/Standards/wm-spec/index.html#NETWMSTRUTPARTIAL)

The question now is: How do I set these properties on a particular window?
