I think we should then replace the example by something simpler. The
point of this tutorial is not to show how to implement a blur. It is
supposed to show some basic concepts of plug-in development. The code
that is used as an example should be simple and bug-free. The current
blur code doesn't seem to fulfill these requirements. So perhaps it
should be replaced by a more local operation.

Another option would be to add a comment to the tutorial that points out
that, for the sake of simplicity, the blur code is simpler than it would
have to be and that it introduces a shift for that reason.

The GIMP source code includes more than hundred plug-ins. I am sure you
will find one or two that can serve as examples.
