Keep doing updates!  More tweaks have been going in.  A few more
yesterday, a few more today.

There's more that can be done to make the program more efficient, but
except for drawing maps, the gain would probably not be worth the
effort.  Right now the symbol() function takes the most CPU if you're
not drawing maps, but it's not a significant amount.

No effort has been expended yet to optimize map drawing.  Seems like
that's the next logical step.
