The skia-compute project is now Spinel, and is under Fuchsia. It is very interesting, perhaps the fastest way to render vector paths on the GPU, but the code is almost completely inscrutable, and it has lots of tuning parameters for specific GPU hardware, so porting is a challenge. Skia has a requirement that rendering of paths cannot suffer from conflation artifacts (though compositing different paths can), as they don't want to regress on any existing web (SVG, canvas) content. That's made it difficult to move away from their existing software renderer which is highly optimized and deals with this well. Needless to say, I consider that an interesting challenge.
