Not really simple. Firstly that does not resolve the problem with ambiguous
state of unmapped windows, since there is sugnificant number of applications
out there that relay on ICCCM compliant IconicState, so even if you unmap
window without setting _NET_WM_MINIMIZED, they will still consider self
iconifyed and start animating its icon window, instead of normal one.
