To achieve this I force memory to a 16-bytes alignment, to achieve this code will allocate 15 extra bytes on the heap but each Block and Frame object will be 8 bytes smaller. Given they are created on the fly and passed around a lot, I think this is a good tradeoff. Not super urgent, but I got it done now, mostly to make sure index is used in a sane way and doesn't take too large values, which would prevent me from making this change later in the future.
