13  *   creation of window when not needed, minimize use of window when it is
34  * - Fix bug in reuse of allocated window after inflateReset()
47  * - Rearrange window copies in inflate_fast() for speed and simplification
48  * - Unroll last copy for window match in inflate_fast()
49  * - Use local copies of window variables in inflate_fast() for speed
56  *   programs like gzip and unzip -- uses window as output buffer to avoid
57  *   window copying
69  * - Changed type of window in inflateBackInit() to unsigned char *
