2 dimensional, translation invariant, 1 phase, loop neighbourhood operation.

The requirements on the NgbT template parameter expressed as class definition are:

template<class ArithT>
class NgbT
{
public:

    typedef HxNgbLoopTag        IteratorCategory;
    typedef HxNgb1PhaseTag      PhaseCategory;
    typedef HxNgbTransInVarTag  TransVarianceCategory;

                                NgbT(HxTagList& tags);
                                ~NgbT();

    HxSizes                     size();
    void                        init();

    void                        next(int x, int y, ArithT value);
    ArithT                      result() const;

    static HxString             className();
};
