+ * This event is sent to BidiSegmentListeners when a line is to
+ * be measured or rendered in a bidi locale.  The segments field is
+ * used to specify text ranges in the line that should be treated as
+ * separate segments for bidi reordering.  Each segment will be reordered
+ * and rendered separately.
+ * <p>
+ * The elements in the segments field specify the start offset of
+ * a segment relative to the start of the line. They must follow
+ * the following rules:
+ * <ul>
+ * <li>first element must be 0
+ * <li>elements must be in ascending order and must not have duplicates
+ * <li>elements must not exceed the line length
+ * </ul>
+ * In addition, the last element may be set to the end of the line
+ * but this is not required.
+ *
+ * The segments field may be left null if the entire line should
+ * be reordered as is.
+ * </p>
+ * A BidiSegmentListener may be used when adjacent segments of
+ * right-to-left text should not be reordered relative to each other.
+ * For example, within a Java editor, you may wish multiple
+ * right-to-left string literals to be reordered differently than the
+ * bidi algorithm specifies.
+ *
+ * Example:
+ * <pre>
+ *  stored line = "R1R2R3" + "R4R5R6"
+ *      R1 to R6 are right-to-left characters. The quotation marks
+ *      are part of the line text. The line is 13 characters long.
+ *
+ *  segments = null:
+ *      entire line will be reordered and thus the two R2L segments
+ *      swapped (as per the bidi algorithm).
+ *      visual line (rendered on screen) = "R6R5R4" + "R3R2R1"
+ *
+ *  segments = [0, 5, 8]
+ *      "R1R2R3" will be reordered, followed by [blank]+[blank] and
+ *      "R4R5R6".
+ *      visual line = "R3R2R1" + "R6R5R4"
+ * </pre>
