Bug 177489 [Viewers] Document usability of IColorProvider, IFontProvider not usable for ListViewers
This week I had this 2 times. Users complaint that IColorProvider and IFontProvider are not working for their ListViewer. I'd like to mention this in the JavaDoc. Question is where the best place for this would be: - in the interfaces itself - in AbstractListViewer#setLabelProvider() or in both places?

    protected abstract void listSetSelection(int[] ixs);
    /**
     * Shows the selection.  If the selection is already showing in the receiver,
     * this method simply returns.  Otherwise, the items are scrolled until
     * the selection is visible.
     */
    protected abstract void listShowSelection();
    /**
     * Deselects all selected items in the underlying widget.
     */
    protected abstract void listDeselectAll();
    /**
     * Adds the given elements to this list viewer.
     * If this viewer does not have a sorter, the elements are added at the end
     * in the order given; otherwise the elements are inserted at appropriate positions.
     * <p>
     * This method should be called (by the content provider) when elements 
     * have been added to the model, in order to cause the viewer to accurately
     * reflect the model. This method only affects the viewer, not the model.

    public void add(Object[] elements) {
        assertElementsNotNull(elements);
        Object[] filtered = filter(elements);
        ILabelProvider labelProvider = (ILabelProvider) getLabelProvider();
        for (int i = 0; i < filtered.length; i++) {
