# note: A skipped 4x4 macroblock between two 16x16 ones that both carry a Y2
#   block.
# expect: ok
# exercises: VP8DecodeMB() clears nz_dc only when the skipped macroblock is
#   not 4x4-coded, so the second 16x16 macroblock sees the Y2 context left
#   behind by the first. Reproducing that quirk is the whole point.
