    fdo#43765, fdo#57884, fdo#58052, fdo#63949: disappearing form controls
    
    Transparent form controls in Writer may not be painted properly, if
    painted from ViewShell::ImplUnlockPaint(true), called from
    SwLayIdle::SwLayIdle.
    
    The problem is that SdrPaintWindow::OutputPreRenderDevice will paint
    the background of the transparent form controls (thus over-painting the
    controls), so it has to be followed by painting the controls themselves.
