Tor Arne Vestbø a1e6fed449 Add Qt::NoTitleBarBackgroundHint window flag 
The flag requests that the window's title bar is drawn without a
background color. This flag is useful in combination with the
Qt::ExpandedClientAreaHint flag, to give the perception that the
window's client area seamlessly blends with the titlebar area
and controls.
