Too small contact images @ scaling x2 (hidpi)

[DanyGee]

Contacts without image set have correct avatar size even @ scaling x2

Contacts avatars get smaller after setting an image @ scaling x2

My hardware

Hmmm... Currently I have no way of testing this, because I don't have a display capable of correctly displaying 2x. But I guess it has to do something with image sizing. I set small ones at 32px and large ones at 64px. I'm gonna investigate and find a solution.
