If I can split up a quaternion to rotations about arbitrary axes then thats
fine - I just need to know how to make that split.
For example if I have a quaternion with some rotation about some axis, I might
need to grab the rotation around (0,0,1) from that quaternion. But I don't see
how to do that right now.
There's a discussion about this at EuclideanSpace:
