It looks like the main fruit of this is piet-gpu[1]. How close would you say it is to stable? And how complete a realisation of the concepts put forth in the OP? I'm currently working on a ui library, and evaluating alternatives for hw acceleration. The whole library wants to be in c, so I would want to rewrite the library by release-time to use it, but don't want to waste time doing that now if it's still really volatile. 1. https://github.com/linebender/piet-gpu https://github.com/linebender/piet-gpu
