Add support for Translate, Scale, Rotate against instances

[Codeglee]

It's a really nifty engine you've written. It would be a great candidate for small turn-based games. For that, we'd need to be able to capture the shape instances and move them rather than cloning them each time.

Is there any chance of that happening? I know that you're hoping to keep the scope small.

The reason why shapes are cloned now is so you can declare shapes with one side, followed by that same slide transformed in various ways, i.e.

var face = new Path([ Point.ORIGIN, Point(1, 0, 0), Point(1, 0, 1), Point(0, 0, 1) ]);

var cubicle = new Shape([
  face,
  face.rotateZ(Point(0.5, 0.5), Math.PI / 2),
  face.rotateZ(Point(0.5, 0.5), Math.PI),
  face.rotateZ(Point(0.5, 0.5), 3 * Math.PI / 2)
]);

Same goes for paths built from translated points. For performance reasons, though, I definitely would like to explore changing a point/path/shape's properties instead of cloning. Not sure how I want the API to look exactly, though. But it is definitely something I'd like to incorporate.
