I am happy you are looking into this issue! This has been bothering me for
a while :)

The current mode works fine for some ref-tests but is really annoying for
others. I would love to have a way to compare the entire page instead of
the viewport.

Maybe it could just be an API on testrunner? Like:
    testRunner.dumpEntirePagePixels()?
