I was mostly thinking the first. The only potentially downside I can think of is that it might be slower -- then again I'm just measuring line-heights, and of these there is (at most) only one line that won't eventually be displayed.

If it were to remain mostly elisp, it would need a reliable way to measure the height of a line (essentially a `st-height' replacement), irrespective of whether it's displayed. It has also proven rather difficult to set the window start "absolutely". I've documented my findings in `st-move'.
