overboard sometimes

System's skyline padding no longer affects vertical spacing because the  
systems are not finalized until after vertical spacing (so that we can do  
stretching within systems at the same time).

It may be possible to add a feature to skylines so that padding is added at  
comparison time instead of when the skylines are built. That might resolve  
the issues raised on the bug list.
