i seem to remember that under nextstep the algorithm was something
like:
while the mouse is below the window:
at some repetition interval t, adjust the current y-coordinate
so that the y-coord that was previously "under" the mouse
is now at the bottom of the window.
that gives a fairly natural proportionality to the thing. of course,
it's not that simple in acme/rio style text windows, where the
scrolling is proportional to the amount of data shown, not the
vertical space taken by the data.

in acme the speed for autoscroll is
proportional to how far out of the window
the mouse is.
that seems to work very well except when
acme is at the bottom of the screen.
then it's much nicer to scroll up.
