MathJax subset to PNG

[rgbkrk]

I'm working on Jupyter notebook support in Zed (zed-industries/zed#9778). I know many researchers that would love to have math formatting via $$. The best interface for me to use in GPUI (what Zed is written with) would be a function that takes a &str and returns raw PNG data. That PNG data can be a Vec<u8> or an ImageBuffer from the image crate. As an example, check out crates/repl/src/outputs.rs from zed-industries/zed#12062.

Is there a subset here that would be on par with MathJax, at least at the level supported in Jupyter notebooks?

I believe using the in-memory IO provider should allow you to drive the engine without doing any file IO. That should allow you to generate a PDF file as a Vec<u8>, after which you would need to use an in-memory PDF-to-image converter.

If you try this and find any APIs lacking, please follow up here or in a new issue with the problems you ran into.
