I didn't check your examples (I'm supposed to be at work :-), but it
all seems well researched. The nice part is that the code for skylines
is already there. The bad part is that my code will have to go. An
afternoon wasted. Well anyways. I'm looking forward to seeing a patch.
I'll check if I have Wanske, otherwise Jan will reply.
