Comment (by Saul Baker):

 Replying to [comment:30 Elon Musk]:
 > You do not understand code at all. It uses quaternions, yaw, pitch and
 roll are fully irrelevant here.

 Internally yes, but the interface exposed to the users is Euler angles, if
 that has surprising behaviour or has usability issues (such as jumping to
 origin when the user's command script stops setting rotations when
 reset_rot!=0) it doesn't matter how excellent a job you've done on matrix
 multiplication.
