 * must be greater than or equal to zero.  The end position must be
 * greater than or equal to the start position, and less than or
 * equal to the length of the text component's text.  The
 * character positions are indexed starting with zero.
 * The length of the selection is
 * <code>endPosition</code> - <code>startPosition</code>, so the
 * character at <code>endPosition</code> is not selected.
 * If the start and end positions of the selected text are equal,
 * all text is deselected.
 * <p>
 * If the caller supplies values that are inconsistent or out of
 * bounds, the method enforces these constraints silently, and
 * without failure. Specifically, if the start position or end
 * position is greater than the length of the text, it is reset to
 * equal the text length. If the start position is less than zero,
 * it is reset to zero, and if the end position is less than the
 * start position, it is reset to the start position.
