For Retina displays, the backing store's size is always 2x the size in points that Cocoa reports. The backing store is then scaled to the display's physical resolution. Also, even if though the default point-size-to-display-physical-pixels used to be 2x, remember that other scaling was always supported. The fact that the default has changed doesn't introduce a *new* problem. Apple always had to have a solution for this.
