# note: An ordinary lossless image, with none of the corners.

# exercises: The control. No transform, no colour cache, no entropy image:
#   whole pixels straight through, which is the one shape every other
#   lossless file here departs from. The four colours differ in all four
#   channels, so the red, blue and alpha codes each carry several symbols
#   and are read once per pixel -- the path a stream takes when
#   is_trivial_literal is false, which a single-colour image never reaches.
