示例1: AddManipulationDevice
/// <summary>
/// Returns a ManipulationDevice associated with the given UIElement.
/// </summary>
/// <param name="element">The target of the ManipulationDevice.</param>
/// <returns>
/// A ManipulationDevice associated with the element.
/// If a device already exists for the element, a reference to that instance
/// will be returned, otherwise a new instance will be created.
/// </returns>
/// <remarks>
/// This function is thread-safe but should be called only on the
/// same thread that 'element' is bound to, due to possibly calling
/// the ManipulationDevice constructor.
/// </remarks>
