20 * Notes:
21 * - Controls with SS_SIMPLE but without SS_NOPREFIX:
22 * The text should not be changed. Windows doesn't clear the
23 * client rectangle, so the new text must be larger than the old one.
24 * - The SS_RIGHTJUST style is currently not implemented by Windows
25 * (or it does something different than documented).
