 		This is a helper spatial node that is linked to the tracking of controllers. It also offers several handy pass throughs to the state of buttons and such on the controllers.
 		Controllers are linked by their id. You can create controller nodes before the controllers are available. Say your game always uses two controllers (one for each hand) you can predefine the controllers with id 1 and 2 and they will become active as soon as the controllers are identified. If you expect additional controllers to be used you should react to the signals and add ARVRController nodes to your scene.
-		The position of the controller node is automatically updated by the ARVR Server. This makes this node ideal to add child  nodes to visualise the controller.

Scrollbars will also automatically resize the grabber based on the minimum_size of the Control relative to the ScrollContainer.  Works great with a [Panel] control.
