The ASCII85InputStream decodes ASCII base-85 encoded data. The exact definition of ASCII base-85 encoding can be found in the PostScript Language Reference (3rd ed.) chapter 3.13.3. IMPORTANT: inherits from InputStream rather than FilterInputStream so that the correct read(byte[], int, int) method is used.
