Someone mentioned xev in this list some days ago, have you tried it?
When I minimize a window, xev tells me this:

UnmapNotify event, serial 18, synthetic NO, window 0x2c00001,
    event 0x2c00001, window 0x2c00001, from_configure NO

so, this UnmapNotify Event might work for you

and when the window is totally hidden, you get:
VisibilityNotify event, serial 18, synthetic NO, window 0x2c00001,
    state VisibilityFullyObscured

and when I change to a different desktop as far as I can see, 
I get that signal as well, you might want to try xev in different environments!

There's a really nice online Xlib manual at:

http://tronche.com/gui/x/xlib/

I found there functions to set icon names, sizes, but not a specific function
to check whether the window is minimized, don't know... I agree with you, a
WM guru is what you are looking for...
