The semantics for overflow detection are a bit tricky with indexed rendering. If the base index in the elements array overflows, then the index of the first element should be used, if the index with bias overflows then it should be treated like a normal overflow. Also overflows need to be checked for in all paths that either the bias, or the starting index location.
