No images in controls when replacing our comctl32 with Windows comctl32 v6 (taken from SxS folder)

ReactOS fails to draw icons for comctl32 controls when replacing our comctl32 by comctl32 v6 taken from Windows 2003.

Also, the debuglog is spammed with (../../win32ss/gdi/eng/alphablend.c:84) BlendFlags != 0 (0x80). I guess Windows comctl32 sets this flags even if MSDN says it must be set to zero.
