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