No, on macOS retina screens it will display raster images at
1/scale-factor size in image-mode, which is 1:1 with physical pixels
on the screen.

If you just insert an image using create-image or in some other
manner, then nothing has changed.

I'm going to try and code up the GTK side of this, and then hopefully
more people can see the behaviour and decide if it's what we want to
happen.
