Usage notes:
- When drawing several passes, a rendering tree with its root node is created for each pass.
- For each node, the local transformations (transformations relative to the “parent") and the world transformations can be obtained and specified.
- When world coordinates of a node are set, its local coordinates are also recalculated, and when local coordinates are set, world coordinates of this node are recalculated.
- For a node that does not have a parent, local and world transformations are the same.
- You can temporarily disable the node (then all its descendants will also be disabled).
