Called if this is our primary **XRInterfaceExtension** before we start processing a :ref:`Viewport<class_Viewport>` for every active XR :ref:`Viewport<class_Viewport>`, returns ``true`` if that viewport should be rendered. An XR interface may return ``false`` if the user has taken off their headset and we can pause rendering.
