# note: An animation frame whose alpha plane is a compressed image stream.

# exercises: The other ALPH compression, inside an animation: the payload is
#   a headerless VP8L stream read by VP8LDecodeAlphaHeader(), and this one is
#   a palette of three alpha values, so it also takes the 8-bit decoding path
#   -- a lossless decode nested inside a frame of an animation, two chunk
#   layers below the file.
