<transform>.getRot() not working

[david]

Hi,
I noticed the function getRot() is not consistent.

I got the following lines in the interactive window:
>>> import vizmat
>>> X = vizmat.Transform()
>>> X.makeRot(0,1,0,180)
>>> X.getRot()
[0.0, -1.0, 0.0, 180.00000500895632]
>>> X.makeRot(0,1,0,90)
>>> X.getRot()
[-0.70710670948028564, 0.0, 0.7071068286895752, 180.00000500895632]

Could someone help out here?

David
