* NOTES
*
* This code was audited for completeness against the documented features
* of Comctl32.dll version 6.0 on Oct. 4, 2004, by Dimitrie O. Paun.
*
* Unless otherwise noted, we believe this code to be complete, as per
* the specification mentioned above.
* If you discover missing features, or bugs, please note them below.
*
* Notes:
* - Windows XP introduced new behavior: The background of centered
* icons and bitmaps is painted differently. This is only done if
* a manifest is present.
* Because it has not yet been decided how to implement the two
* different modes in Wine, only the Windows XP mode is implemented.
* - 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).
*
* TODO:
* - Animated cursors
