# note: The VP8X animation flag set on a file with no animation chunks.
# expect: reject
# exercises: The flag alone is enough: WebPParseHeaders() turns any file
#   claiming animation into UNSUPPORTED_FEATURE, since a still decoder cannot
#   compose frames. Nothing looks for the ANIM chunk the flag implies.
