A quaternion dtype will probably make into the next version of numpy
will be able to replace ~1/3 of the transformations.py module.
The transformations.py module was shortly discussed on the numpy list in
I had an off list discussion on how to integrate some of the functions
in numpy/scipy. Consent was that if such a module makes it into
numpy/scipy it should :
1) support any float dtypes
2) support 2D, 3D, and 3D homogeneous coordinates.
3) support both "column vectors on the right" and "row vectors on the
