    Updates the renderer based on updated values from the data source. For example, if a new unique value gets added to the FeatureClass, in case of unique value renderer, it gets updated with the newly added value. Similarly with class breaks renderer, it tries best to preserve the number of class breaks and recalculates the break values based on the updated values. This method must be called on the MCT. Use QueuedTask.Run.
