18 nearly the requested output block size. The first pass generates
20 output size plus a specfied excess amount (see the EXCESS define

31 requested size minus an amount to allow the compressed stream to
34 requested size. Assuming sufficient input and a requested size
39 before filling the requested output size, then that compressed
47 out the requested size, and small enough so that the final deflate
