listener

an object implementing the Audio listener protocol

Outputs

orientation

an audio-orientation

Word description
Returns the orientation of the listener. The orientation must be returned in an audio-orientation tuple with the following slots:

•	forward is a 3-component vector indicating the direction the listener is facing.
•	up is a 3-component vector indicating the "up" direction for the listener. This vector does not need to be normal to the forward vector.

The vectors do not need to be normalized.
