As discussed on https://github.com/mathjax/MathJax/pull/1723 a follow up change to
T105310
could be to use improved sizing operation as explained here
https://github.com/mathjax/MathJax/issues/566#issuecomment-257555181
.
I think that's something nice to have even though it would take a while until all images are re-generated.
Any objections?
