Under what circumstances do you use more than one device pixel per CSS
pixel? Does it require the user to turn on UI scaling on Mac?

Regardless, I bet that most people using Webkit to write scripts using
getImageData still get it wrong, because they have normal screens.
Implementing high-res backing store in more browsers won't solve this
problem, not until the average developer has a high-dpi screen. But I repeat
myself.
