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?
