Great news! I'm super excited to see this go in!

Re: Intent to implement and ship: CSS and SVG filters for canvas 2D
Markus, Tobias, and Tantek will update the wiki page with our proposed normative text. Our key use case here is Shumway, where graphics filter implementations in JS code have not (yet) been able to offer acceptable performance characteristics in Canvas2D. We've proven that it's polyfillable in other browsers, though with the performance characteristics already mentioned. Because of the Shumway dependency, we'll ship it even if we have to call it mozCanvasFilters or hide it behind a Shumway pref--do you have a preference on this? I'd rather not hide the feature as I believe it's useful for the Web at large, especially for applications currently using the Flash Player for filter effects. --Jet On Mon, Jun 15, 2015 at 4:05 PM, Xidorn Quan quanxunz...@gmail.com wrote: On Tue, Jun 16, 2015 at 3:15 AM, Markus Stange msta...@themasta.com wrote: Summary: The filter property on CanvasRenderingContext2D allows authors to specify a filter that will get applied during canvas drawing.
