PS6, Line 272:   poly.outer().emplace_back(xmin, ymin);
             :   poly.outer().emplace_back(xmax, ymin);
             :   poly.outer().emplace_back(xmax, ymax);
             :   poly.outer().emplace_back(xmin, ymax);
             :   poly.outer().emplace_back(xmin, ymin);
Is there a reason for this being counter-clockwise?
polygon2d is defined as clockwise:
using polygon2d = bg::model::polygon<point2d, true>;
so this is a reverse-oriented polygon (not sure if that's intended or not)
