What happened to the effort to create CSS filters programmable in GLSL?
Wasn't that effort addressing canvas filters too? Programmable filters
seem more desirable than a fixed set. Last I heard the CSS filters
effort was exploring ways to limit filter operations to those that would
not allow, for example, the visited state of links to be determined. I
think allowing operations only on same-origin data solves those types of
issues for canvas.
