I don't think it matters if it is inflate or deflate. ZLib keeps an 
internal state depending on the data. That is the whole reason why the 
packing is so good: it uses the redundancy in the data already seen to 
construct a codebook. (And that's also the reason why you can't start to 
deflate in the middle.)
