Bug 181978 – [Web Animations] Expose getKeyframes() and parsing of remaining keyframe properties

• Component: Animations
• Status: RESOLVED FIXED

[Antoine Quint]

There are a few properties left on keyframes (composite and easing) that we don't support yet as well as the getKeyframes() method to expose the parsed keyframes.

If this returned a RefPtr<TimingFunction> you wouldn't need the &foo.get() at the calling sites.

Are these accurate enough? (no rounding errors?)

We don't do step-start or step-end?

Will fix in commit.

Will look into that.

Not that I have found in my testing.

On macOS WK1 the test http/wpt/web-animations/interfaces/AnimationEffectTiming/easing.html is failing consistently. It looks like the expectations changed for the test were not correct for this.

Would this just need a rebaseline or is this something deeper?
