If I chose to validate using getClientRects() (or some other API) then I
expect I'd be using dumpAsText() instead of DumpRenderTree output. That
seems OK to me, too. And if I'm using the API to validate, my checks could
have a bit of tolerance to account for platform font differences. So I would
not necessarily need to use Ahem.
