quite a few things are being done, but they won't be released for a
little while (all right, it's because i've spent time thinking about
what to do but only just started on the graphics side, because of time
required for other things).

providing rio's interface on other systems is one thing, but
on plan 9, it seems more attractive in many cases (to me)
to use draw and rio directly.  the all of inferno-in-a-window
becomes a special case of that.
