frustum culling chunks?

[max-mapper]

when looking at the draw call previews in the WebGL inspector in newer Chrome i'm seeing a lot of draw calls for things that aren't in the view frustum.

apparently three.js has built in frustum culling but I imagine we could do it better if we did it manually?

Should take care of the test for you. Integrating with 3.js is another matter...
