Fixed is a strong word. TODO: I have solved the problem by using isEmpty to tell when it's a fresh AABB
and just returing the passed AABB as the new expanded AABB. This feels lazy and I expect it'll cause issues in the future.
Plus it isn't truely correct and the context which uses it could just use the first obj AABB since there is only 1 object
Working on fixing issues with the BVH implementation.
Commiting a working changes version. Code has been cleaned up considerably.
A proper code review is nessacary in the near future.
