- * @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.
