Detailed Description

Composition scene class.

The base of the demo in Demopaja is scene. The layers are store inside the scene. Scene also contains information about the size of the canvas where the demo is shown and the speed of the demo.

The changes made to the scene is saved to a undo object if present.

This class is implemented by the system.
