* A top-level AS can contain 2^24 children and a bottom-level AS can contain 2^24
* triangles. At a branching factor of 4, that means we may need up to 24 levels of box
* nodes + 1 triangle node
* + 1 instance node. Furthermore, when processing a box node, worst case we actually
* push all 4 children and remove one, so the DFS stack depth is box nodes * 3 + 2.
