Title: Fix for jank measurement when `letter-spacing` is set.

@nathansobo This doesnt really work. It only works if we measure all the characters in the line all the time. Even then, though, there are cases it's off a little bit. Ugh. If you have any suggestions, glad to hear them, but thinking i'll just wontfix #3054 and have them use `px`.
