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  *
