- getters/setters are no more in Vector3
- object hierarchies thus don't use "isDirty"
- this was completely killing performance for anything that was touching a lot of Vector3 like creation of meshes and dynamic buffers
- even without this, performance of hierarchies went up (a lot)
- objects do not get passed renderer anymore
- camera was almost also removed, but this is useful for LOD (though there may be some cleaner way to do this?)
- material ids are now unified, this makes "geometry.sortFacesByMaterial" faster (thus scene init / GUI blocking is shorter)
- all WebGL examples should work now (render-to-texture has weird lights and in some camera control feels different)
- CanvasRender still broken, despite many efforts :(
- currently only points and lines work, faces don't show up. I think this may need assistance from mrdoob.
