/**
* Extends IBaseLabelProvider with the methods
* to update the label for a given element. The label is represented by a
* ViewerLabel.
* Unlike ILabelProvider, this allows the text and image to be
* set in the same request, rather than via separate requests.
*
* It also allows the current values for the text and image to be considered by
* the label provider, allowing for potential optimizations.
* For example, decorating label providers that run in the background can hold off
* applying an update to a previously populated label until the decoration is ready,
* thereby reducing flicker.
