* @type: FT_Stream_OpenGzip
*
* @description:
* open a new stream to parse gzip-compressed font files. This is
* mainly used to support the compressed *.pcf.gz fonts that come
* with XFree86
*
* @input:
* stream :: target embedding stream
* source :: source stream, used to
*
* @return:
* error code. 0 means success
*
* @note:
* the source stream must be opened _before_ calling this function.
*
* calling @FT_Stream_Close on the new stream will *not* call
* @FT_Stream_Close on the source stream. None of the stream objects
* will be released to the heap.
*
* the stream implementation is very basic, and resets the decompression
* process each time seeking backwards is needed within the stream
*
* in certain builds of the library, gzip compression recognition is
* automatic when calling @FT_New_Face or @FT_Open_Face. This means that
* if no font driver is capable of handling the raw compressed file,
* the library will try to open a gzip stream from it and re-open
* the face with it.
*
* this function may return "FT_Err_Unimplemented" if your build of
* FreeType was not compiled with zlib support.
