Greetings,
I think that there's a bug in coordsyst.pyx, revision 1.22, and that
the little patch below is correct.
Incidentally, the quaternions are reversed from what I'm used to;
e.g., no-rotation corresponds to [0,0,0,1], while I was expecting
[1,0,0,0]. Is this a common convention?
Cheers,
Rory
