Hey, I was going to check in on your overall progress and I saw this issue, so I wanted to point out the Google fonts repo has something that does a good job at this in the tools folder.

https://github.com/google/fonts

Are you referring to https://github.com/google/fonts/blob/master/tools/compare_font.py? Correct me if I'm wrong, but that script compares things like sizes of glyphs and supported subsets, and doesn't render any images.

The script in this issue renders image diffs like https://camo.githubusercontent.com/a1621cf63d7e06d5843e3b0704d85cbe4f4a96c4/687474703a2f2f692e696d6775722e636f6d2f555143376144512e706e67.

Right. I don't mean to reference that tool as a competing item, but something you may draw from.

Thanks for the suggestion Jerry. I will check out the Google fonts repo to see what they have.
