  20  * NOTES
  21  *
  22  * This code was audited for completeness against the documented features
  23  * of Comctl32.dll version 6.0 on Oct. 4, 2004, by Dimitrie O. Paun.
  24  *
  25  * Unless otherwise noted, we believe this code to be complete, as per
  26  * the specification mentioned above.
  27  * If you discover missing features, or bugs, please note them below.
  28  *
  29  * Notes:
  30  *   - Windows XP introduced new behavior: The background of centered
  31  *     icons and bitmaps is painted differently. This is only done if
  32  *     a manifest is present.
  33  *     Because it has not yet been decided how to implement the two
  34  *     different modes in Wine, only the Windows XP mode is implemented.
  35  *   - Controls with SS_SIMPLE but without SS_NOPREFIX:
  36  *     The text should not be changed. Windows doesn't clear the
  37  *     client rectangle, so the new text must be larger than the old one.
  38  *   - The SS_RIGHTJUST style is currently not implemented by Windows
  39  *     (or it does something different than documented).
  40  *
