FIX: show retina avatars on Chrome (#11480) 

chromium may report float device pixel ratio below 1.5 that is still clearly retina:

```
window.devicePixelRatio
1.4999998807907104
```

We used to round this down to 1 and not provide these browsers with retina avatars.

New algorithm is much more forgiving, anything over 1.1 gets 2x images, anything over 2.1 gets 3x images.
