Ghostty's sprite renderer got a major refactor by our font maintainer (Qwerasd). We now support more sprites and they line up perfectly on cell edges. Additionally, our sprites now pack more efficiently on the GPU to save some VRAM. Comparison between terminals as an example.

Ghostty's always had a built-in sprite renderer (actually, rasterizer). The job of the rasterizer is to generate pixel-perfect sprites dynamically for a given grid size.

Practically, this results in much more aesthetically pleasing shell prompts, powerline bars, etc. And things like circles that line up perfectly make for better TUIs.

Some additional amazing background: the rasterizer uses a 2D graphics library written in Zig specifically for Ghostty by a community member (but generalized: https://github.com/vancluever/z2d). And while I wrote the initial rasterizer, the major work since has been by our font subsystem maintainer Qwerasd who has taken it to new, incredible levels. ❤️
