+  * @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.
