protected override HitTestResult HitTestCore(PointHitTestParameters hitTestParameters)
{
    Point pt = hitTestParameters.HitPoint;

    // Perform custom actions during the hit test processing,
    // which may include verifying that the point actually
    // falls within the rendered content of the visual.

    // Return hit on bounding rectangle of visual object.
    return new PointHitTestResult(this, pt);
}
