           Summary: [chromium] Update scroll-mechanism from
                    GestureRecognizer
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: sadrul at chromium.org


This patch updates how the gesture-recognizer performs scroll: Instead of just sending a series of 'GestureUpdate' events, send a single 'GestureBegin' event, followed by a series of 'GestureUpdate' events, and end with a 'GestureEnd' event.

This change is covered by existing tests (e.g. fast/events/touch/touch-gesture-scroll.html). A series of subsequent patches will update how the EventHandler processes the ScrollUpdate gesture-event, add support in EventSender to send gesture-update events from the DRT, and include additional layout tests.
