 anything that runs process_command is setting the yaw/pitch/roll state to
 zero and then not moving the quaternion from origin when
 {{{reset_rot!=0}}}, snapping the view back to 0,0,0 for example a pan up
 followed by a small zoom:

 I merged the lines when copying it over so may have messed it up: but
 believe that was functional, your way would be my natural suspicion for
 correctness though.
