I was confused too. There's no mention of current implementations. It's like half an encyclopedia article missing the good half. For example, TLDraw has it's own inking algorithm of pressure+velocity+path -> generated outlines comprised of bezier curves. InkCanvas in Microsoft implementations afaik is closed-source. Is there a standard library for ink for the pencil in macos? Or does everyone roll-their-own on the mac side?
