title: Sizes for iOS 8 backgrounds?
body: <p>So I have all my resources scaled up to @3x, but I don't know what size to scale up my background images to. I currently have them at 640x1136 for @2x, but this would mean 960x1704 for @3x which is going to look pixelated on a 1080x1920 device. What do I do for these background images?</p>
