I was changing the behaviour of this controller, and wondered if there was some way to make it less branchy and more self-documenenting.

I remembered an idea of Dave Thomas's - thinking about programs as series of transforms - and tried to apply it.

Which do you prefer?

	var dimensions = {
	x: [Infinity, -Infinity],
	y: [Infinity, -Infinity],

	var axisToDeltas = {
	x: "width",
	y: "height",
	};
