Just use blend2d - it is CPU only but it is plenty fast enough. Cache the rasterization to a texture if needed. Alternatively, see blaze by the same author as this article: https://gasiulis.name/parallel-rasterization-on-cpu/

ThorVG might be worth a look - open source (MIT), ~150KB core, GPU backends (WebGPU, OpenGL).

We are using it as official dotLottie runtimes, now a Linux Foundation project. Handles SVG, Lottie, fonts, effects.
