    x11: Use the currently focused X window for _NET_ACTIVE_WINDOW
    
    MetaDisplay and MetaX11Display focus windows are slightly decoupled,
    we cannot rely here on the MetaDisplay focus to be updated yet. We
    however know the X Window that got focused, so lookup the corresponding
    MetaWindow (and client X window) from it.
