* \brief Set the region from a reference image

* Change the region of a label map to be the same as one of a reference image.
* This filter implements the same feature as its superclass, but with the input region
* well integrated in the pipeline architecture.
* If the output cannot contain some of the objects' lines, they are truncated or removed.
* All objects fully outside the output region are removed.
