+ *     This allows for sophisticated hovers in a way that information computed by
+ *     the hover can be displayed in the best possible form.</li>
+ * <li>{@link dwtx.jface.text.source.IAnnotationHoverExtension2} since
+ *     version 3.2 allowing a text hover to specify whether it handles mouse-wheel 
+ *     events itself.</li>
+ * </ul></p>
