        float blend = b[i];
        if (base < 0.5) {
            result[i] = 2.0 * base * blend;
        } else {
            result[i] = 1.0 - 2.0 * (1.0 - blend) * (1.0 - base);
        }
    }

        float blend = b[i];
        if (base < 0.5) {
            result[i] = base * (blend + 0.5);
        } else {
            result[i] = 1.0 - (1.0 - base) * (1.0 - (blend - 0.5));
        }
    }

Operator OP_HARD_LIGHT = 8

    for (int i = 0; i < 3; i++) {
        float base = a[i];
        float blend = b[i];
        if (base < 0.5) {
            result[i] = base * (2.0 * blend);
        } else {
            result[i] = 1.0 - (1.0 - base) * (1.0 - 2.0 * (blend - 0.5));
        }
    }

Operator OP_MAX = 9

Represents the size of the Operator enum.
