Hi Oshima,

Can I have an OWNERS review for this CL?

Thanks!

Don't you have a bug for this? If not, can you file one?

Is this for all platforms? If so, please put it in common/
subdirectory, and you need an asset for 200 percent as well.

FYI: CQ can't commit binary files. You need to dcommit them.
