Markus is moving with great speed and we should have the necessary Moz2D support landed soonish.
I think the biggest outstanding issue is how to spec the canvas API for this. The most obvious approach to me is to add a "filter" attribute to CanvasRenderingContext2D that takes a CSS filter value and applies it during the compositing step of each drawing operation. Unfortunately CSS3 filters doesn't have a value representing a general color matrix. You could use "context.filter = "url(#mysvgColorMatrixFilter)" and set up the corresponding <filter> element subtree in the document, but that's a bit naff for JS users (and wouldn't work in Workers). The data: URL version of that is even more naff and might also not work in Workers. So, we could choose between a) Add CanvasRenderingContext2D.filter and a color-matrix(N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N) CSS filter value. b) Add CanvasRenderingContext2D.colorMatrix which allows direct setting of a color matrix on the canvas, more like what Tobias suggested. This would allow later adding CanvasRenderingContext2D.filter as a separate feature. (If both were specified, both would be applied in some specified order.) Any thoughts?
