IPointableCanvas Interface

This interface characterizes something which contains a UnityCanvas which can be the target of Interaction SDK "pointer interactions." Commonly, this is used to implement screen-like interactions (for menus, etc.) in otherwise 3D experiences and applications: the Unity Canvas can be used to create a 2D interface just as it would be for traditional screen-based experiences, and the Interaction SDK's PointerInteractor<TInteractor, TInteractable>s allow XR users to interact with this UI in ways that are usable and familiar.
