Some REST APIs like /changes/ may return an "avatars" object within
the account with the avatar URL that /accounts/${id}/avatar would
redirect to:
"owner": {
"_account_id": 10...,
"name": "Shawn Pearce",
"email": "sop@google.com",
"avatars": [
{
"url": "https://somegooglesite.com/.../photo.jpg",
"height": 26
}
]
},
This can save an entire 302 redirect request with the backend server,
whose latency can be significant when displaying 25 rows on HTTP 1.1
when the browser is limited to 3 or 4 concurrent requests.
