I was trying to be careful on always create then on demand like
before. E.g. I was thinking maybe this container shouldn't exist when
there's no display at all.
But looks like init_displaystate() is indeed always invoked for system
code.. so yeah, perhaps I can move it over too, and drop this patch (below
will be part of last patch to use objects_get_container() instead, or part
of its splits).
