It's nice to see that SVG is getting serious about custom filter effects[1], and with any luck, compositing[2]. [1]: http://www.w3.org/TR/2012/WD-filter-effect

  I don't foresee CSS shaders shipping in any browser. The proposal is fundamentally at odds with pretty much every browser's accelerated graphics stack, and forces falbacks to slower, power-hungry modes of operation. The filtered results are independent of hit testing, meaning a filtered element can visually appear in an entirely different location than the corresponding hit target. The security implications are downright frightening, including leakage of image data, history, and other state across origins.
