  * @function:
  *   FT_Stream_OpenLZW
  *
  * @description:
  *   Open a new stream to parse LZW-compressed font files.  This is
  *   mainly used to support the compressed *.pcf.Z 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, LZW 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 LZW 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 LZW support.
