I suspect that the pattern I use right now for inheritance (John Resig) has some performance impacts.

Compare it with the Ctor pattern to see if the perfromance can be improved.

General optimizations

To avoid conflicts in global scope

When calling setPosition on a SceneNode object, the transformation matrix is completely overwritten. We should only overwrite the translation part in the matrix.

2 caches:

1. Cache the value after doing a find() on this.Values in the get() method.
2. Cache the value retrieved from the transition.

Right now the position and the orientation of a SceneNode are bounded by the transformation matrix. They should be decoupled in a way that enable us to do something like this:

SceneNode.Orientation.follow(path)

This way, only the orientation of the SceneNode will change over time while following the path.
