           Summary: Expose an entry point to Chrome for scrolling portions
                    of the page
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Enhancement
          Priority: P2
         Component: WebKit API
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: rjkroege at chromium.org


It is desirable under certain circumstances (inertial scroll for example) for the Chromium RenderWidget to be able to request portions of the contained WebWidget to scroll as if it were the target of mouse wheel events. I propose adding a method gestureScroll to the WebWidget in chromium/public/WebWidget to provide this functionality: calling gestureScroll results in the same behaviour as pixel precision wheel events to the specified positions in the WebWidget.
