We need to determine how KWin should treat activities. Atm. they're basically implemented as non-exclusive clone of VDs but there seems to be user assumption they're rather subsessions. This impacts things as geometry, focus chain VD assignemt and even what to do when closing a window or in other terms: Is the client on activity #a the same as on activity #b (and what if it's on all?) or are those different clients which manage the same WId? If it's still the same client - where should it differ? Reproducible: Always
