Why no longer an `image.view()` here?

I note that
```
In [18]: image.image.view()
Out[18]: <galsim._galsim.ImageViewF at 0x109d9d9f0>
```
whereas
```
In [19]: image.view()
Out[19]: <galsim.image.Image at 0x109f4d810>
```
which seems fairly significant, but I don't really get the difference I admit!

Also, I note that the method  `image.view()` as well as being still callable does have a docstring, but it is not mentioned in the description of methods in the `galsim.Image` docstring... is that intentional due to some sort of deprecation of this method?
