# note: The same sweep for the two block kinds a 16x16 macroblock has: the
#   Y2 block and the luma blocks that follow it.
# expect: ok
# exercises: Types 1 (Y2) and 0 (luma after Y2). The luma blocks start at
#   position 1, so band 0 is unreachable for them and band 1 is what their
#   neighbour context selects. One Y2 block per macroblock means the four
#   macroblocks are what give it contexts 0, 1, 1 and 2.
