Draw the Ceiling in red if preferences are marked for that.

Browse source 
This code actually uses the preferences for something. It will show and
hide the calculated ceiling in red if the prefrerences are changed for
that. One bad thing that I did in this commit ( so it was easy to try ) is
that a preference change will redraw the whole graph - not optimized. I'll
make this better in a later commit so that only the affected items will be
redrawn.
