* @function:
* 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 ::
* The target embedding stream.
*
* source ::
* The source stream.
*
* @return:
* FreeType error code.0~means success.
*
* @note:
* The source stream must be opened _before_ calling this function.
*
* Calling the internal function `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
* automatically handled 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 gzipped stream from
* it and re-open the face with it.
*
* This function may return `FT_Err_Unimplemented_Feature’ if your build
* of FreeType was not compiled with zlib support.

* @function:
* FT_Gzip_Uncompress
*
* @description:
* Decompress a zipped input buffer into an output buffer.This function
* is modeled after zlib’s `uncompress’ function.
*
* @input:
* memory ::
* A FreeType memory handle.
*
* input ::
* The input buffer.
*
* input_len ::
* The length of the input buffer.
*
* @output:
* output::
* The output buffer.
*
* @inout:
* output_len ::
* Before calling the function, this is the the total size of the
* output buffer, which must be large enough to hold the entire
* uncompressed data (so the size of the uncompressed data must be
* known in advance).After calling the function, `output_len’ is the
* size of the used data in `output’.
*
* @return:
* FreeType error code.0~means success.
*
* @note:
* This function may return `FT_Err_Unimplemented_Feature’ if your build
* of FreeType was not compiled with zlib support.
