Cross-linking the scikit-image thread on this.

Support for array types other than NumPy

I created a repo that has a demo of dispatching to different backends with a uarray-based approach Benchmark results and some discussion is given the README there. I mostly autogenerated the uarray multimethods on the scikit-image side using a script provided in the repository above, but it does create an additional layer of indirection that can make things a little harder for new contributors to understand. The Dask backend there is a more user-friendly way of using apply_parallel where a use…
