| 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.
