Any reason this is outside of the container div? It seems like it might make more sense to have it in there, given that we have most other stuff (inventory, info, stats, etc) inside there.

The only reason this might matter is if we want to make the game half res for really slow computers, having everything inside one container makes a change like this almost trivial to make.

However, it's possible that we still want the UI elements to be fullscreen in this case, and only half the resolution of the game view. I'm not sure. What do you think?
