- * @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 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
