lily/skyline.cc:393: Skyline::Skyline (Building b, Real start, Axis
horizon_axis, Direction sky)
This isn't quite what I had in mind (for one thing, it means that the
caller has to be aware of buildings, calculating their slope, etc.)

what about
Skyline::Skyline (vector<pair<Point, Point> > const& segments, Axis,
Direction)?

it works similarly to Skyline::Skyline(vector<Box>...) except that the
resulting skyline shows the outline of the given set of line segments.

lily/skyline.cc:647: out.merge (to_merge);
merge is linear, so this loop is quadratic.
