            Bug ID: 203568
           Summary: [Web Animations] Cache the output of getBasicTiming()
                    and getComputedTiming() for animation resolution
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Animations
          Assignee: webkit-unassigned at lists.webkit.org

At the moment, running a CSS transition will yield these calls to AnimationEffect::getBasicTiming() and AnimationEffect::getComputedTiming():

>>>>> DocumentTimeline::updateAnimationsAndSendEvents()
    getBasicTiming() in WebAnimation::effectEndTime(), localTime is 0.017000.
    getBasicTiming() in WebAnimation::effectEndTime(), localTime is 0.017000.
    getBasicTiming() in WebAnimation::computeRelevance(), localTime is 0.017000.
    getBasicTiming() in AnimationEffect::getComputedTiming(), localTime is 0.017000.
    getComputedTiming() in DeclarativeAnimation::invalidateDOMEvents(), localTime is 17.000000.
    getBasicTiming() in WebAnimation::effectEndTime(), localTime is 0.017000.
    getBasicTiming() in WebAnimation::effectEndTime(), localTime is 0.017000.
<<<<< DocumentTimeline::updateAnimationsAndSendEvents()
    >>>>> TreeResolver::createAnimatedElementUpdate()
        getBasicTiming() in AnimationEffect::getComputedTiming(), localTime is 0.017000.
        getComputedTiming() in KeyframeEffect::apply(), localTime is 17.000000.
    <<<<< TreeResolver::createAnimatedElementUpdate()
    getBasicTiming() in WebAnimation::effectEndTime(), localTime is 0.017000.
    getBasicTiming() in WebAnimation::effectEndTime(), localTime is 0.017000.
>>>>> DocumentTimeline::updateAnimationsAndSendEvents()

Ideally, we should reduce this to a single call to getBasicTiming() and getComputedTiming().
