+   "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.
