Description
Hi,
i've experienced interoperability problems with
gst zlib and other zlib implementations (eg. Compress::Zlib perl module).
It seemed to came down to the window size init value
of -15, which seemed incorrect. The documentation
of zlib recommends a (default) value of 15.
The attached patch should fix that.

If you want a window size of 15, use InflateStream. -15 is used by RawInflateStream, which is the class you want to use if for example you're decompressing ZIP files.

Ok, never mind then. Sorry for my confusion, the patch did indeed break
even interop with itself :)
