This seems to make a bunch of assumptions that aren't, in general,
true in CSS.

In particular, it assumes that all the lines end up the same height
(which is true only if there are no variations in font or vertical
alignment, and might even require that there be no variation in
which fonts are selected as a result of character-by-character
fallback), that there are no floats anchored within the text that
you're trying to balance.
