something wrong with 2-cells

[juan_gandhi]

I've upgraded presheaf to render 2-cells, like this:

A \rtwocell^f_g{\alpha} &B



The problem is, dvipng does not render the down arrow properly.
I wonder if anybody knows anything or if anybody cares.

> stop using png at all

Yep. I don't quite understand who can need dvitopng if there is MathJax.

Also five six years ago exporting to pdf then exporting from pdf to format need usually produced much more visually appealing results than direct transition. ImageMagik usually did the trick
