Surely this is an issue with the Info viewer as the Info file itself
does not have a size for text?

I tried this myself in emacs (I installed emacs specially for this).
You can open an Info file with "C-u C-h i FILENAME".

The images is generated correctly for displaymath, just most of it is
off the edge of the screen as the images are far too big for the
text.  See screen shot.  The horizontal lines come from the image.

We could ask Emacs users or developers if there is a way to make
the images be displayed smaller in Info mode.
