Speaking of performance, replace

fence.getXs()[0], fence.getYs()[0], fence.getXs()[1], fence.getYs()[1]);

with
vector<double> const x = fence.getXs();
vector<double> const y = fence.getys();
x[0], y[0], x[1], y[1]);

and you are 50% of vector<double> copies less.

As SelectionBox is represented by 4 elements only, std::array would be cheaper.
