+safe to process the rest of the block.  If Largest Reference is greater than
+zero, the encoder transforms it as follows before encoding:
+
+~~~
+   LargestReference = LargestReference mod 2*MaxEntries + 1
+~~~
+
+The decoder reconstructs the Largest Reference using the following algorithm:
+
+~~~
+   if LargestReference > 0:
+      LargestReference -= 1
+      CurrentWrapped = TableLargestAbsoluteIndex mod 2*MaxEntries
+
+      if CurrentWrapped >= LargestReference + MaxEntries:

OK.  As long as it works.
