The lack of support for filters on Canvas makes Safari fails a number of tests

I can find 84 files mentionning ctx.filter on WPT
https://github.com/search?q=repo%3Aweb-platform-tests%2Fwpt+ctx.filter&type=code
It doesn't mean that all of them are relevant but some will fail.

I avoided the tentative, and I might have missed some of them.
