 Blocks are accessed in two different orders in the various decoder processes.
-The first is \term{raster order}.
+The first is \term{raster order}, illustrated in Figure~\ref{fig:raster-block}.
 This indexes each block in row-major order, starting in the lower left and
  proceeding along the bottom row, followed by the next row up starting on the
  left, etc.

 The second is \term{coded order}.
 In coded order, blocks are accessed by super block.
 Within each frame, super blocks are traversed in raster order,
