Josh, I decided to go with your original recommendation of using std::max(1, alignment) for each block calling set_alignment. It's not really the set_alignment functions job to make a decision on what the caller meant when they passed in a number; it just protects against incorrect values. The guy that calls the set_alignment function should make sure it's passing the right value. It's a bit more work this way (although mostly I expect people to copy-and-paste), but this makes more sense.
