Re: set_display_context_callback() and incorrect pagination

Ok, so we need a sliding window of siblings around a fixed point, but the
siblings_callback is returning an iterator over all siblings.  So perhaps
the way to solve this is to extend siblings_callback to handle a limit and
an offset.  Then you can do:

  $theme->siblings($something + 1, $position - $something)

and that'll just iterate over the small set of siblings that you care
about.  How does that sonud?  I can probably get that checked in pretty
quickly if you think that'll work.
