High resolution equations for printing, Retina displays (hi-dpi)

Description

Author: fredrik.orderud

Description:
Math formulas in printed articles does not look good, since they are rasterized
for screen rendering (~100DPI), which is far coarser compared to printers (>300DPI).

Would it be possible to generate equations of higher resolution in the
"printable version" of wiki-articles?

With higher-resolution images rendered for high-res displays (bug 32696) we can trigger them in on the print stylesheet as well as for the density media queries (bug 32697).

Replacing dep on bug 32696 (render high-res math images) with bug 32697 (use MathJax). It produces scalable output which is even nicer!

I corrected again the dep, MathJax should be bug 31406.

Reopening bug 32696 and adding it back; it may be easier to set up the multiple-resolution output with texvc than to get MathJax fully ready to be the default. Particularly for printing, there are problems with MathJax. :(

What kind of problems are you having with MathJax? We're aware of one bug on our side (https://github.com/mathjax/MathJax/issues/386) which will be fixed with the upcoming 2.2 release.
