A renderer/rendering library for something as simple as a text editor is not (or is not supposed to be) a lot of code and should not take up a large amount of space in a binary. Odds are good it's the embedded Treesitter grammars and other things that Zed uses that takes up space.
It is Rust software, so there is probably a good 50-90% waste when it comes to just raw needed vs. actual lines of code in there, but there is no way anyone makes a renderer so overcomplicated that it takes up a meaningful part of the 500 MB or so Zed takes up on Windows.
