            Bug ID: 179293
           Summary: [Web Animations] Refactor ScriptedAnimationController
                    to share functionality with DocumentTimeline
           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

As part of https://bugs.webkit.org/show_bug.cgi?id=179236, we are integrating with DisplayLinkRefreshMonitor to run the DocumentTimeline. However, ScriptedAnimationController implements much of what we need to do, throttling and fallback to a timer if DisplayLinkRefreshMonitor is unavailable are two facilities we need for DocumentTimeline. We should refactor ScriptedAnimationController into a more general purpose animation supporting object and make both rAF and DocumentTimeline integrate with it.
