Admin bar avatar dimensions

[linuxologos]

Since [18683] the avatar is called as 28x28 (it used to be 16x16). It seems, that matches the total admin bar height. However it is forced to 16x16 through CSS

#wpadminbar .quicklinks li#wp-admin-bar-my-account.with-avatar > a img {
    ...
    height: 16px;
    width: 16px;
    ...
}

I don't know if there's a reason for this inconsistency.

Say there is a reason. If avatar does get 28x28, adding the 1px border, it ends up as a 30x30 item, which overflows the height of the admin bar and seems a bit ugly.

Some plugins may use the value of size given in get_avatar() to pass inline styles. In such case, default CSS (16x16) is overridden and the problem is obvious.

If we really want the avatar to be a 16x16 img, get_avatar() should perhaps be given that exact value. If there's some reason and get_avatar() should be given a greater value, then the maximum should possibly be a 26x26 (let 2 px for top+bottom borders).
