Controller Tooltips

Overview

This adds a collection of Object Tooltips to the Controller that give information on what the main controller buttons may do. To add the prefab, it just needs to be added as a child of the relevant alias controller GameObject.

If the transforms for the buttons are not provided, then the script will attempt to find the attach transforms on the default controller model.

If no text is provided for one of the elements then the tooltip for that element will be set to disabled.

There are a number of parameters that can be set on the Prefab which are provided by the VRTK_ControllerTooltips script which is applied to the prefab.
