    [COMCTL32] Address regression CORE-14622
    
    "Avira Antivir Personal 6.35.00.243" had issues painting its
    setup wizard dialog with correct background color.
    That part was a regression of SVN r74136 == git
    b1b42795a94d8e3cb69e2d9e5bd0af4929610361
    
    and also did not draw its umbrella bmp, which did never work
    in ros up to now afaik.

    Thanks to patches author Doug Lyons and HBelusca.
    
    Wine has been reported to be affected by that bug as well:
    https://bugs.winehq.org/show_bug.cgi?id=46636
    Not sure whether our patch will be accepted by Wine,
    to my naive eye this looks like an interim solution.
