My understanding is that the filter should be designed to work over the
Region.

A related question that I have is:  How can a filter request a larger
Region (Buffer) from its inputs (i.e. suppose an algorithm needs the whole
image as a Region).  Is this handled automatically or must it be managed
by the pipeline architect (user)?
