Priority wise I think we need to work on the API. We need to include boost
and other c++ experts. But in general, we need to answer the question what
we want from gil? Do we just want the core and the ability for extensions?
The core being sort of a STL for 2D data or do we want to include 3D?

I think we should stick with the concepts that gil already provides and
take that as a starting point.

There are ideas here:

I would advise against backward compatibility.
