    As you can see here, the function that Unity is wrapping is Box2D's "QueryAABB".
    You can also see that QueryAABB is 1/3 the computation time of OverlapAreaNonAlloc.

    I'm confused that this wrapper would cause so much overhead. Is there anything that can be done to fix this? This takes up over 15% of my computation time right now for the project I am working on.
