I did something zooming a decade ago. If I remember right at a Dante
meeting first. It was the time that I got questions from the audience
why I was concerned about mathml and math in context as latex and
backslashes were all one needs.
Page 2 etc: click on small 'rectangles' will zoom in, while clocking at
the edge will zoom out.
So, I wondered if the tex file still processes in mkiv but given that I
used some low level mkii hook I had to change a few lines. Anyway, a
good reason to mkiv the s-pre-17 style (one can just run the file to get
an example).
In the new beta.
