Is it possible to know if a full-screen application has started?

[Jasper St. Pierre]

You can use SubstructureNotifyMask on the root window and look for the
ConfigureNotify/MapNotify events, and look at what size an application
requests, I'm not sure what Warzone2100 does, but if it uses the standard
extended window manager hints, you can also subscribe to PropertyNotify and
look out for changes to _NET_WM_STATE to see if it changes to
_NET_WM_STATE_FULLSCREEN.
