 * This test applies the redaction using the {@link StrictPdfCleanUpProcessor}

 * removed if it is <b>completely</b> inside the redaction zone . The original
 * removes also text located merely <b>partially</b> inside the redaction zone.
 * Furthermore this test uses a larger redaction zone to check whether text
 * completely contained in the redaction zone really is removed.
