Bug 154064 Need a way to access the TreeItem or TableItem on a refresh
It is not currently possible to know when an item is refreshed. This is required for ownerDraw support in viewers.
bundles/org.eclipse.jface/src/org/eclipse/jface/viewers/ViewerColumn.java
if (label.hasNewText())
			item.setText(columnIndex, label.getText());
		if (label.hasNewImage())
			item.setImage(columnIndex, label.getImage());
	}
*/
	/**
	 * Refresh the TableItem for element.
	 * 
	 * @param item
	 * @param element
	 * @param columnIndex
	 */
/*	public void refresh(TableItem item, Object element, int columnIndex) {
		ViewerLabel label = new ViewerLabel(item.getText(columnIndex), item
				.getImage(columnIndex));
		getLabelProvider().updateLabel(label, element, columnIndex);
		if (label.hasNewBackground())
			item.setBackground(columnIndex, label.getBackground());
		if (label.hasNewForeground())
			item.setForeground(columnIndex, label.getForeground());
		if (label.hasNewFont())
			item.setFont(columnIndex, label.getFont());
		if (label.hasNewText())
			item.setText(columnIndex, label.getText());
		if (label.hasNewImage())
			item.setImage(columnIndex, label.getImage());
