"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.
