And done. The remaining errors where due to using complex64 instead of
and the small gaussian filter error is due to the fact that .sum() in
numarray defaults to .sum(dtype='d') even for float32 arrays.
All tests of nd_image pass for me and I've moved nd_image as a scipy
This is a great day indeed. I've wanted this for some time.....
