scene.moveWorld(x, y) translates every object by (x, y).
By placing scene.moveWorld(-pos) into any moving geometry, it allows said geometry to always be at the center of the world, [0, 0].
This entirely fixes the problem of bit precision error at long distances, by making the center of the world right on top of potentially intricate components that don't work past no-man's land!
It's surprising there is little documentation on this particular saint of a function, because it's almost too good to be true!
