 * A <code>IDocumentInformationMapping</code>  represents a mapping between the coordinates of two

 * the corresponding information of the image and vice versa.
 *
 * In order to provided backward compatibility for clients of <code>IDocumentInformationMapping</code>, extension
 * interfaces are used to provide a means of evolution. The following extension interfaces
 * exist:
 * <ul>
 * <li> {@link dwtx.jface.text.IDocumentInformationMappingExtension} since version 3.0 extending the
 *      degree of detail of the mapping information.</li>
 * <li> {@link dwtx.jface.text.IDocumentInformationMappingExtension2} since version 3.1, adding lenient
 *      image region computation.</li>
