Translation invariant, n phase pixel import operation.

Pseudo code of the operation:

InPixOp(Out, PixOp)
{
    for p = 1 to PixOp.nrPhases();
    {
        PixOp.init(p)
        foreach o in Out
            Out(o) = PixOp();
        PixOp.done(p)
    }
}

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

template<class ArithT>
class PixOpT
{
public:
    typedef HxPixOpInTag            DirectionCategory;
    typedef HxPixOpTransInVarTag    TransVarianceCategory;
    typedef HxPixOpNPhaseTag        PhaseCategory;

                        PixOpT(HxTagList&);

    ArithT              doIt();

    int                 nrPhases() const;
    void                init(int phase);
    void                done(int phase);

    static HxString     className();
};
