         * need to compare the gradient magnitude to that in the
         * direction of the gradient; only if the value is a local
         * maximum do we consider the point as an edge candidate.
         *
         * We need to break the comparison into a number of different
         * cases depending on the gradient direction so that the
         * appropriate values can be used. To avoid computing the
         * gradient direction, we use two simple comparisons: first we
         * check that the partial derivatives have the same sign (1)
         * and then we check which is larger (2). As a consequence, we
         * have reduced the problem to one of four identical cases that
         * each test the central gradient magnitude against the values at
         * two points with 'identical support'; what this means is that
         * the geometry required to accurately interpolate the magnitude
         * of gradient function at those points has an identical
         * geometry (upto right-angled-rotation/reflection).
         *
         * When comparing the central gradient to the two interpolated
         * values, we avoid performing any divisions by multiplying both
         * sides of each inequality by the greater of the two partial
         * derivatives. The common comparand is stored in a temporary
         * variable (3) and reused in the mirror case (4).
