Looks like there were still reftest failures: https://hg.mozilla.org/integration/mozilla-inbound/rev/9713cb1ed642

Comment on attachment 626693 [details] [diff] [review] Use a value of 0.2 [Approval Request Comment] User impact if declined: Slower curve drawing performance. The spinning svg tiger goes from 6.5fps to 7.5fps on my phone Testing completed (on m-c, etc.): Has been on m-c for a couple of days Risk to taking this patch (and alternatives if risky): Mobile only, very low risk as it's just changing a constant. String or UUID changes made by this patch: None
Comment on attachment 626693 [details] [diff] [review] Use a value of 0.2 [Triage Comment] While this doesn't block release, the risk profile is low enough (and SVG usage uncommon enough) to take this on Aurora 14. Approved.
