Add this attribute to a method to get a notification just before building the scene.
A method with this attribute will also get called when entering Playmode, when Application.LoadLevel or Application.LoadLevelAdditive is called.
PostProcessSceneAttribute has an option to provide an order index in the callback. This lets you change the order in which the callback is invoked. (Builtin callbacks always have a value of 0).
