Sure. And I know about these. The original poster was talking about languages with HTML+CSS+JAVASCRIPT as compile targets, not canvas, svg or webgl. I'm simply addressing his comment.

Either way, WebGL/canvas operate as child elements in an html page, you still need to use javascript, and SVG isn't GPU accelerated. It's still, overall, an ugly mess. But definitely, with improvements, canvas, svg and webgl are all candidates for my aforementioned "next steps."
