apply_neighborhood: What to return when an overlap is used?

[m-mohr]

Process ID: apply_neighborhood

Describe the issue:
What I’m not clear about when working with the process is: If you specify overlap, what is expected to be returned from the callback? the data with or without overlap?

Proposed solution:
Actually, how easy is it to detect what the overlap and what the actual data is? In the end, it's probably easier to return the data with overlap, but the back-end discards any changes to the overlap and only replaces the values for the "actual data" without overlap.
