New issue 851: ray object fields are out of order
Ray objects no longer return fields in order along the ray from the start to the end
position. This can be seen with the following:
ds = load(...)
ray = ds.ray(start, end)
The t values should go increase monotonically from 0 to 1, but instead are scrambled.
This can be worked around with an argsort of the fields, but I think this is still a bug,
or at least a regression.
