Small fixes

1: FIXED TODO

Added var renderer = new THREE.WebGLRenderer({antialias: true});

It will now use the dom element.

Though it will give you an error for not defining THREE, it runs perfectly fine
I don't think this is actually what we want, there is already a renderer being created and attached to $rootWorld, this one would be a different instance, and while it may appear that the calculations are correct, I bet it's actually creating a whole new canvas element
