When a scene anchor is instantiated, a and/or is added if the underlying scene anchor as a 2D and/or 3D component, respectively.

Both and provide the option to scale and offset all child objects, so that they align with the dimensions of the scene anchor.

If this type exists on the scene anchor's child objects, then a scale/offset will only be performed if the type aligns.

Note: if this type does not exist on the scene anchor's child objects, then the will take precedence for scaling/offseting child objects.
