+ *
+ * @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.
