 /*
    "KateViewSpaceStatusBarSeparator"
    A 2 px line to separate the statusbar from the view.
    It is here to compensate for the lack of a frame in the view,
    I think Kate looks very nice this way, as QScrollView with frame
    looks slightly clumsy...
    Slight 3D effect. I looked for suitable QStyle props or methods,
    but found none, though maybe it should use QStyle::PM_DefaultFrameWidth
    for height (TRY!).
    It does look a bit funny with flat styles (Light, .Net) as is,
    but there are on methods to paint panel lines separately. And,
    those styles tends to look funny on their own, as a light line
    in a 3D frame next to a light contents widget is not functional.
    Also, QStatusBar is up to now completely ignorant to style.
