I am not sure whether `delimiter` is the best key. I think that `scale`
may be better, but using `scale` for specifying the scaling of math
delimiters will be inconsistent with how `scale` is used everywhere
else. Another option is to use `alternative` key.
it would be something factor=2 or so, not the funny XxXxxxXX kind of
flags
Sure. factor=(auto|none|1|2|3|4) is also ok (and would be directly
mapped to choosemathbig).
actually we will hook into a new feature of luatex for specifying the
size of delimiters (so no vbox hack) .. factors are multipliers of
