The application can listen to the ActivityStopped DBUS signal and see
if any window it owns is affected because of this. From the POV of
this approach, if anything undesirable happens, it is because of a bug
in the application and not because of a bug in KWin, releasing KWin
from any responsibility in the Activity handling.
