Update the Spatial. Updating it will update the transformation, lighting, and bounding properties if they are dirty. This is mainly used internally, as initiating will propagate the scene world bounding to the root node, after its children and their children are updated (if a Node). Update order: 1. Controllers 2. World Transform 3. World lighting 4. Children (if Node) 5. World Bounding 6. Propagate Bound (if initiator)
