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