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.
