> Surrounding box, w/ proportions of the box (ratio 3 width : 1 height)

I don't understand this part. The aspect ratio of the box seems much more extreme than 3:1.

It is. I downloaded their image and it's like 540x128 or so. If it were 512x128 it would be 4:1, but it's slightly larger, like 4.2:1 (er... 21:5?). I was highly confused by that as well.
