Together, these metrics will give us information on the graphical timeline

respond to user input with low latency
Will we be able to get this information during CI-style automated
runs? I would like to start recording these and watching for
regressions. I don't much care if they are accessed via JS APIs or
through some other mechanism, just that they are exposed some way we
can get at them in automation.

We could add a flag that prints meaningful messages to stdout for
top-level browsing contexts when these timestamps are recorded. Seems
like it shouldn't be a big deal.
Cheers,
