Details

Currently to implement an SVG color matrix filter, for example, we need to do three filtering passes:

  1. sRGB to linear
  2. Multiply
  3. linear to sRGB

This is quite expensive on SW-WR and probably isn't great on real GPUs either.

Instead we should have the option of doing the conversion as part of the filter.

Nical, do you have time to look at this in the near term? If we can get something that's upliftable to 88 that would be great.

I'm going into this in the near future. I don't think anything will get uplifted though.

This will be fixed when I get https://phabricator.services.mozilla.com/D174208 to land :)
