The world's root slot is unique and always at the top of the world slot hierarchy. It has a fixed position at [0; 0; 0], fixed identity rotation, and [1; 1; 1] scale. This means that, for a slot parented directly under the world root, global and local coordinate measures will be equivalent. This is also true if and only if all of a slot's parents have [0; 0; 0] position, [0; 0; 0] rotation, and [1; 1; 1] scale.
