       The <code>org.eclipse.jface.viewers.LabelProvider</code> and <code>org.eclipse.jface.viewers.ColumnLabelProvider</code> classes now
       support lambda functions for their <code>getText()</code> and <code>getImage()</code> methods.
       This is provided through the new static methods <code>createImageProvider()</code> and <code>createTextProvider()</code> respectively.
       <p>
         For use cases where the LabelProvider should implement both the <code>getText()</code> and <code>getImage()</code> methods, the static method <code>createTextImageProvider()</code> can be used.
