indent-bars.

This package manages to display straight lines irrespective of operating
system screen scale value or Emacs scale-mode value other than 0.

As long as indent-bars mode doesn't use other drawing primitives than what
(display-fill-column-indicator-mode) is using, I think the stipple
behaviour of (display-fill-column-indicator-mode) contains a bug.
