refactor PIL.image to pillow.image

[Reimar Bauer]

We should check if we could replace PIL to pillow

http://pillow.readthedocs.io/en/4.0.x/

We in fact already use pillow. meta.yaml requires pillow and pillow offers the PIL module. And pillow lives in the PIL namespace (that is, there is no pillow module). Installing PIL overwrites pillow(also PIL) actually and confuses conda quite a bit.

[Reimar Bauer]

we never should overwrite pillow by PIL.

I have not had a detailed look on this yet. So it is a remark more than a bug or task to verify that it is completly solved

[Joern Ungermann]

No, not we overwrite PIL, pillow does. pillow and PIL share the same namespace (i.e. PIL) and I really do not see how one could install both in parallel. But conda does not care. We require in meta.yaml pillow.

We can close this issue for MSS.
