Fixed an error in handling of bad zlib CMINFO field, found by American Fixed an error in handling of bad zlib CMINFO field, found by American
Fuzzy Lop. Fuzzy Lop, reported by Brian Carpenter. inflate() doesn't immediately
fault a bad CMINFO field; instead a 'too far back' error happens later
(at least some times). pngfix failed to limit CMINFO to the allowed
values but then assumed that window_bits was in range, triggering an
assert. The bug is mostly harmless; the file can't be fixed.
