Meaningful Paint is intentionally missing, since Blink's current
definition relies on the Blink-internal concept of "layout objects".
Translating this into something usable for Servo will require discussion
with people more familiar with our layout implementation than I
currently am.

Oh, and as for how I expect they'll be implemented:
Time to interaction sounds straightforward to me - on a
per-script-thread basis, track the start of the last 10s window that did
not contain a task that took longer than 50ms to execute. Whenever at
