Remarks

Reparenting nodes is subject to many restrictions. For example, some nodes cannot be moved, others would break the document if moved. Below are possible exceptions that can be thrown if the operation is invalid.

If this is called on an auto-layout frame, calling this function can cause this layer to be resized and children to be moved.
