       'to' lists below is carefully designed to be a factor of 3. That way

       our reference file (which checks against a one third complete animation)

       can contain whole numbers, which is necessary to avoid failure due to

       hard coded rounded numbers in the reference not matching platform

       specific rounding behaviour.
