55
  * @description:
 
56
  *   Open a new stream to parse LZW-compressed font files.  This is
 
57
  *   mainly used to support the compressed `*.pcf.Z' fonts that come
 
58
  *   with XFree86.

  * @input:
 
61
  *   stream :: The target embedding stream.

  *   FreeType error code.  0~means success.

  *
 
68
  * @note:
 
69
  *   The source stream must be opened _before_ calling this function.
 
70
  *
 
71
  *   Calling the internal function `FT_Stream_Close' on the new stream will
 
72
  *   *not* call `FT_Stream_Close' on the source stream.  None of the stream
 
73
  *   objects will be released to the heap.
 
74
  *
 
75
  *   The stream implementation is very basic and resets the decompression
 
76
  *   process each time seeking backwards is needed within the stream
 
77
  *
 
78
  *   In certain builds of the library, LZW compression recognition is
 
79
  *   automatically handled when calling @FT_New_Face or @FT_Open_Face.
 
80
  *   This means that if no font driver is capable of handling the raw
 
81
  *   compressed file, the library will try to open a LZW stream from it
 
82
  *   and re-open the face with it.
 
83
  *
 
84
  *   This function may return `FT_Err_Unimplemented_Feature' if your build
 
85
  *   of FreeType was not compiled with LZW support.
