I do not see how allowing to specify that pixels outside the defined
rectangle for a buffer by
definition is for instance the smeared out values (or the mirrored
values) of the defined content
would yield a different result from handling this inside the operation itself.

Doing it this way keeps the blur operations clean and simple and moves
the complexity down in the abstraction layers.
