+ *                there are no other break opportunities in the line.
+ * eNormalBreak   The line has a break opportunity determined by the standard

+ *
+ * Future expansion: split eNormalBreak into multiple priorities, e.g.
+ *                    punctuation break and whitespace break (bug 389710).
+ *                   As and when we implement it, text-wrap: unrestricted will
+ *                    mean that priorities are ignored and all line-break
+ *                    opportunities are equal.
