    {
        base.OnStylusDown(rawStylusInput);
        rawStylusInput.NotifyWhenProcessed(null);

    }

    protected override void OnStylusDownProcessed(object callbackData, bool targetVerified)
    {
        base.OnStylusDownProcessed(callbackData, targetVerified);

        Dispatcher renderingThreadDispatcher = this.GetDispatcher();
        renderingThreadDispatcher.BeginInvoke(DispatcherPriority.Normal, new WorkerMethod(DoSomething));
    }

    private void DoSomething()
