I think the "validation" invariant which Selection currently tries to hold, is
a wrong one.  In at least I don't think Selection should assume that both of
it's endpoints are valid visible positions.  Maybe we need a separate
VisibleSelection class which holds that invariant, similar to how we have
VisiblePosition and Position split classes.
