示例1: GetNextPropertyChangePosition
/// <summary>
/// Returns the closest neighboring TextPointer in an indicated
/// direction where a property value calculated from an embedded
/// object, scoping text element, or scoping highlight could
/// change.
/// </summary>
/// <param name="textPosition">
/// Position to query.
/// </param>
/// <param name="direction">
/// Direction of content to query.
/// </param>
/// <returns>
/// If the following symbol is TextPointerContext.EmbeddedElement,
/// TextPointerContext.ElementBegin, or TextPointerContext.ElementEnd, returns
/// a TextPointer exactly one symbol distant.
///
/// If the following symbol is TextPointerContext.Text, the distance
/// of the returned TextPointer is the minimum of the value returned
/// by textPosition.GetTextLength and the distance to any highlight
/// start or end edge.
///
/// If the following symbol is TextPointerContext.None, returns null.
/// </returns>
