lawnjelly 2527067c4d Partially revert change to BVH render tree update method 
Leaves in the bug fixes, but reverts the change to the update method.

Turns out the new update method of getting the scenarios was causing problems, I will need to consult with reduz on the best way of getting access to the scenarios for a single update per frame.

Doing multiple updates isn't terrible but it should be nicer to get a single update working, as it should be more efficient, and give a single point for pairing callbacks.
