    33The next question then would be:
    44
    5 since when `y >= ( 3 << nScale )`, `32 >> ( ( y << 1 ) >> nScale )`, i.e. `wT[x]`, is equal to 0, there seems no need in Eq (8-257) on `refT[x][y]` to explicitly include the condition check of `( y < ( 3 << nScale ) )`, as `mainRef[dX[ x ][ y ]]*wT[x]` would be equal to 0 in this case anyway.

    77So, should we remove the `( y < ( 3 << nScale ) ?` and `( x < ( 3 << nScale ) ?` condition check from Eq (8-257) and Eq (8-262), respectively?
