My research retreat was very productive. I didn't quite finish implementing sparse multisampled path rendering on GPU, but I got close (hopefully soon). I ran into a performance snag but have a good idea how to fix it.
But the real fruit is probably ideas for even higher quality path rendering - a hybrid of analytical area AA and multisampling - and also compositing. Expect to hear more before long.
@raph how much do you think people care about higher quality antialiasing? Skia is looking like they are going all in with MSAA in graphite and that kind of swayed my confidence that better is really needed
