Comment (by Michael Koch):

 Replying to [comment:35 Saul Baker]:
 > I'd also note it's not limited to commanding the rotation angles,
 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:

 'lerp(-15.0000,-15.0000,TI)';

 I'm surprised that this line works for you. I get an error message when I
 omit [expr] before the second v360.
