it's terrible, only culling 3%, but it's fast, only taking 60ns
~60% more cycles during BFS (~0.5ms, 225->355ns per section) in exchange for 5-25% more chunks culled.

I was hoping that Vector3f would help more but at this point I might as well just bite the bullet and add 12 float member variables.this currently breaks when outside of the world bounds (like too high up)-- no chunks render
