I'll send a note to webkit-dev before landing this.

This seems strange. People are going to have files disappearing from their working trees without any explanation. I think it would be a lot better to just do a one-time delete of all .checksum files in the WebKit tree and commit that separately.

I said I would send a note to webkit-dev before landing this :)

But if you prefer, I can update the existing pngs and remove the .checksum files first.  The downside is there will be a window of time between the patches (or patches created before the .checksum delete and landed after) where people will be checking in .checksums after I've deleted all of them.  I guess I can just do a second pass a week later.

Seems like the steps could be:

1) Embed checksums in all existing PNGs
2) Change ORWT not to read or write .checksum files
3) Delete all .checksum files

These could each be done separately.

That sounds fine to me.  This is part of step 2 (the read part is done).  I'll come back and r? this once step 1 is done.

The ORWT changes look good to me. Someone more familiar with NRWT should review that part.

(1) is done.  This is (2).  I'll send a note to webkit-dev after landing this.  It'll be harmless if people continue to check in .checksum files for a few days.  They'll just be ignored.

maybe this check should be driver_output.image instead of driver_output.image_hash now?

I switched this before committing.  There's a lot of code in NRWT that we can update/delete now, but I'll do that in a follow up patch.
