BUGS
----
(i.e. *not* new ideas for features or things still unfinished)

* Redraw weirdness:  when a "partial" redraw of GoCanvas occurs (due
  to a small exposure event) the red dot isn't redrawn.  When a "full"
  repaint() of GoCanvas happens, the red dot *is* redrawn.

* Karl needs to optimize do_move()'s search for dead groups.  It's
  butt slow, and especially noticeable when loading up a large SGF
  stream.

* Fix stupid IE4/IE5 error.  C'mon folks... that's 50% of the browsers
  out there.  Let's at least make ONE of them work!  Ignoring this
  problem causes such a distribution problem that it should be
  considered a bug, not a feature.
