    tdf#127022 vcl: fix Windows RTL menu bar
    
    Regression from commit e8d5b8beb5958147235ff955ed38c47b51d860ff
    (tdf#113714 vcl menu bar window: avoid flicker, 2019-05-20), the problem
    was that while the original render context has RTL set up correctly, the
    intermediate virtual device had it disabled all the time.
