           Summary: [WK2][GTK] Let DrawingArea manage
                    setAcceleratedCompositingWindowId
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebKit Gtk
        AssignedTo: webkit-unassigned at lists.webkit.org

This is a preparation patch for Threaded Coordinated Graphics.

    LayerTreeHost uses a native window handle to make glContext for
    accelerated compositing. Therefore it is natural for DrawingArea to take
    responsibility for the native window handle. And, in Coordinated
    Graphics case, WebPage creates LayerTreeHost before receiving a native
    window handle from UIProcess. Therefore we need a method to set the
    native window handle to already created LayerTreeHost.

    This patch uses DrawingAreaProxy::setNativeCompositingSurfaceHandle
    instead of WebCoreProxy::setAcceleratedCompositingWindowId to set window
    ID for accelerated compositing.

    Also, this patch renames the setAcceleratedCompositingWindowId with a
    more generic name, setNativeCompositingSurfaceHandle.

    No new tests. No change in functionality.
