* Relative lookup fix
Some of the transforms weren't being transformed, added another test.
* test
* better test
* Reduce any-entities-intersecting tests
* Minor allocs reductions
Added a poly struct with the intention of replacing the existing one whenever I finish box2c port.
* fix merges
* Revert some stuff
* Poly tests
* Heavily optimise entitylookup
Previously I made it so MOST of entitylookup goes through the same 4 or 5 codepaths and uses shapes. The downside was some codepaths were made much slower in the process.
This fixes most of the going up and down lookups that some codepaths did. It should also be faster than the pre-shapes version because GetLocalPhysicsTransform is being used for the non-approx queries and most entities are parented directly to their broadphase.
* Tests and confidence
* code
* dang
