Using Game dimensions in a model definition within a scene is not correct when greater than 640 x 480.

[burtlo]

When a developer uses the Game.dimensions or Game.center within a scene to populate a model property it is actually set to the default value of 640 x 480 and not to the actual value of the game.

class FirstScene < GameScene
  draw :hero, position: Game.center
en

In this example the hero will be drawn at 320 x 240.

This is likely because of these class methods being interpreted before the metro game file has been properly calculated.
