+ * From the PDF Reference
+ * <pre>
+ * The RunLengthDecode filter decodes data that has been encoded in a simple
+ * byte-oriented format based on run length. The encoded data is a sequence of
+ * runs, where each run consists of a length byte followed by 1 to 128 bytes of data. If
+ * the length byte is in the range 0 to 127, the following length + 1 (1 to 128) bytes
+ * are copied literally during decompression. If length is in the range 129 to 255, the
+ * following single byte is to be copied 257 ? length (2 to 128) times during decompression.
+ * A length value of 128 denotes EOD.
+ *
+ * The compression achieved by run-length encoding depends on the input data. In
+ * the best case (all zeros), a compression of approximately 64:1 is achieved for long
+ * files. The worst case (the hexadecimal sequence 00 alternating with FF) results in
+ * an expansion of 127:128.

+ * methods. The parent PushBackInputStream is not used in any way and
+ * all methods are overridden. (Thus when adding new methods to PushBackInputStream
+ * override them in this class as well!)
+ * unread() is limited to the number of bytes already read from this stream (i.e.
+ * the current position in the array). This limitation usually poses no problem
+ * to a parser, but allows for some optimization since only one array has to
+ * be dealt with.
+ *
+ * Note: This class is not thread safe. Clients must provide synchronization
+ * if needed.
+ *
+ * Note: Calling unread() after mark() will cause (part of) the unread data to be
+ * read again after reset(). Thus do not call unread() between mark() and reset().
