 The data in the property is an array of atoms specifying the window types 
(the real one and fallbacks). So for your specific case you just read the 
property, cast the data to long, and loop over it until you either find the 
atom value for the window type you want or until you reach the end of the 
data.

 If you grep for 'dirty & WMWindowType' in this file
http://webcvs.kde.org/cgi-bin/cvsweb.cgi/kdelibs/kdecore/netwm.cpp?rev=1.136&content-type=text/x-cvsweb-markup , 
that's the KDE code for reading the _NET_WM_WINDOW_TYPE property, if that 
helps you. 'WMState' is for _NET_WM_STATE.

 What exactly is supposed to be 'window id of the maybe-iconic state'?
