# note: A horizontal upscaling hint of 1 and a vertical one of 3.

# exercises: Two of the four values of the two 2-bit scale fields;
#   lossy-frame-scaled has 3 and 2 and lossy-frame-scale-2 the rest, so
#   between them every value of both is written. libwebp reads them into
#   pic_hdr and acts on neither.
