	// if we had a parent before and it still contains this node...
	if (oldParent != null && oldParent.children.contains(this)) {
		// remove it
		oldParent.removeChild(this);
	}
	// make sure newParent contains this node
	if (!newParent!.children.contains(this)) {
		newParent.appendChild(this);
	}
}
