A bit of investigation shows that annotate-padding in paper-system.scm is not 
adapted to the new skyline code.
It may be trying to get the touching point and/or max heights of empty 
skylines.  It is also potentially calling car and cdr on Y-ext and next-Y-ext 
which, as the comment above the function suggests, may be skyline pairs (I'm 
not sure if this is a problem...).
