Lgtm! Before committing this, can you send a simple short PSA to blink-dev in
case anyone is using this locally? No need to wait for a response. Send the
email and commit whenever you want!

Thanks so much for doing this! If I find other work like this in the future,
should I send it your way?

<old man screaming at cloud>
what about all the docs that mention --dump-render-tree? and the command line
flags that include -drt-? and all the code comments about dumprendertree?
