Thank you; this is better, but still not perfect. I left an example on
the GitHub issue https://github.com/dspinellis/cas2svg/issues/1

The character images in https://github.com/simh/simh/issues/754. They
appear pixelated to me, rather than vector drawn.
The US3653001A patent text in
https://patents.google.com/patent/US3653001A/en refers to pixels:
"The method of picture formation on the CRT display is point plotting on
a 1,024 X [,024 raster, i.e., lines and characters are formed from
closely spaced points. "
This is what confused me.
