 53  * @function:

 55  *
 56  * @description:
 57  *   Open a new stream to parse gzip-compressed font files.  This is
 58  *   mainly used to support the compressed `*.pcf.gz' fonts that come
 59  *   with XFree86.
 60  *
 61  * @input:
 62  *   stream ::
 63  *     The target embedding stream.
 64  *
 65  *   source ::
 66  *     The source stream.
 67  *
 68  * @return:
 69  *   FreeType error code.  0~means success.
 70  *
 71  * @note:
 72  *   The source stream must be opened _before_ calling this function.
 73  *
 74  *   Calling the internal function `FT_Stream_Close' on the new stream will
 75  *   *not* call `FT_Stream_Close' on the source stream.  None of the stream
 76  *   objects will be released to the heap.
 77  *
 78  *   The stream implementation is very basic and resets the decompression
 79  *   process each time seeking backwards is needed within the stream.
 80  *
 81  *   In certain builds of the library, gzip compression recognition is
 82  *   automatically handled when calling @FT_New_Face or @FT_Open_Face.
 83  *   This means that if no font driver is capable of handling the raw
 84  *   compressed file, the library will try to open a gzipped stream from
 85  *   it and re-open the face with it.
 86  *
 87  *   This function may return `FT_Err_Unimplemented_Feature' if your build
 88  *   of FreeType was not compiled with zlib support.
