Bug 181857 – [Web Animations] Expose timing properties (delay, endDelay, fill, iterationStart, iterations, direction) and getComputedTiming()

• Component: Animations
• Status: RESOLVED FIXED

[Antoine Quint]

We need to expose most of the timing properties on AnimationEffecTiming, namely:

- delay
- endDelay
- fill
- iterationStart
- iterations
- direction

… and also AnimationEffect::getComputedTiming() which exposes the computed values for those properties and some of the already-exposed properties.

Wouldn't this be the default value anyway?

Add some default values here.

Could you just put this in an existing header that is already included by everything?

Good point, I'll check.

These are _always_ computed, I'm not sure there's any value in that.

None that I could find.
