Good point.  So any "unusual" character which ends up selecting
a different font that happens to be slightly taller will disrupt the
"conservative" scroll.

Tho, I guess we should consider "1" as meaning "strictly smaller than
2.0", in which case a line would have to be twice as tall as a normal
line before we cause a recenter.

Fair enough.
