The spec has received a fair amount of input from the CSS and SVG working groups, and particularly from Apple, Google, Mozilla, Opera and Adobe.

A followup: we're going to start work on the CSS Shaders proposal [1] soon. Adobe have published their implementation which was specific to Chromium, and we'll be working with them to split it into small patches that can land in the coming weeks. A good introduction to the technology is [2].

This will be done behind the ENABLE_CSS_FILTERS macro, but also with the guards for ENABLE_WEBGL since the implementation (and security) requirements are so similar.
