IPointableCanvas Interface
This interface characterizes something which contains a Unity Canvas 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.
The Unity Canvas to which users can "point" in order interact with the UI implemented within.
