This filter stream decompresses a stream that is in zlib or gzip format.
Note that reading the gzip format requires zlib version 1.2.1 or greater,
-(the builtin version does support gzips).
+(the builtin version does support gzip format).
The stream is not seekable, \helpref{SeekI()}{wxinputstreamseeki} returns
{\it wxInvalidOffset}. Also \helpref{GetSize()}{wxstreambasegetsize} is
<wx/zstream.h>

+If the parent stream is passed as a pointer then the new filter stream

The {\it flags} wxZLIB\_ZLIB and wxZLIB\_GZIP specify whether the input data
is in zlib or gzip format. If wxZLIB\_AUTO is used, then zlib will
autodetect the stream type, this is the default.
%if WXWIN_COMPATIBILITY_2_4
This version is not by default compatible with the output produced by
the version of {\it wxZlibOutputStream} in wxWidgets 2.4.x. However,
-there is a compatibilty mode, which is switched on by passing
-wxZLIB\_24COMPATIBLE for flags. Note that in when operating in compatibilty
+there is a compatibility mode, which is switched on by passing
+wxZLIB\_24COMPATIBLE for flags. Note that in when operating in compatibility
mode error checking is very much reduced.

This stream compresses all data written to it. The compressed output can be
in zlib or gzip format.
Note that writing the gzip format requires zlib version 1.2.1 or greater
-(the builtin version does support gzips).

Creates a new write-only compressed stream. {\it level} means level of
compression. It is number between 0 and 9 (including these values) where
0 means no compression and 9 best but slowest compression. -1 is default
value (currently equivalent to 6).
+If the parent stream is passed as a pointer then the new filter stream
+takes ownership of it. If it is passed by reference then it does not.

The {\it flags} wxZLIB\_ZLIB and wxZLIB\_GZIP specify whether the output data
will be in zlib or gzip format. wxZLIB\_ZLIB is the default.
