Detailed Description

Scrollbar indicator.

It's a dumb indicator: it does not react to keyboard events (class FIXME does it instead)

Appearance details:

Suppose we have a horizontal scrollbar 10 cells wide: ~~===~~~~~ The visible part of the scrolled contents is indicated by the BAR, here 3 cells wide. (The bar is also known as "slider", "puck", "elevator")

Unlike in GUIs we have no arrows at the ends of the scrollbar because we can't read the mouse clicks anyway.

If the scrollbar gets shrunk to size 1 or 2, it is drawn with arrows meaning there is something in the pointed direction.
