After I was able to get the behavior to be almost right (using lines as the
unit) by re-approximating "max value" at the moment "cur value" became equal
to "max value", I switched to chars as the unit, and it smoothed things out
to my satisfaction. I guess the approximation is better using smaller
units, and so the difference between reality and the scrollbar state is
smaller.
Thanks,
