I don't think this has anything to do with the problems. The current
typesetter places the gap between the "line height" and real "text
height" above the text, which is probably what's causing the text to
appear further down. (In other words, the text touches the lower edge of
the line height rectangle.) I'll change this so the gap is below the
text instead. (So the text touches the upper edge of the line height
rectangle.)

I should have been clearer. It isn't the point size of the text that's
too high, it's the line height. Anyway, I could add some magic when
placing the baseline when the container is too small to fit anything,
but I'd prefer not to. I think moving the text up (in it's line height)
will take care of this in all sane cases. :)
