_DELTAQ must be 0
AV1E_SET_ENABLE_SUPERRES must be 0
Thus, at least, "-lossless" does have a different meaning from "-crf 0",
so I think it would be useful to add "-lossless" flags.

Hi, Moritz.
Yeah, you are right! And sorry.
After the discussion, I will move this change from "lossless patch" to
"gray patch".
Thanks.
