Some of tis is testable by passing all our test cases, right?  Or did you have
something else in mind?

Do we have anything that measures "performance" for regressions?

I suspect that the performance on MathML with complicated row structures
isn't going to be good at the moment.  There are two many multiple
rendering passes for operator and content stretching and that can probably
be optimized.  On the other hand, it seems to do quite well on "reasonable"

What is involved in (2) ?

I'm happy to try to beat on the code to make sure it works well
enough for people to feel comfortable turning it on.
