Comment:

 In 43524.2.patch: Add two more "default" image sizes. These sizes are
 added to the `$_wp_additional_image_sizes` array and not stored in
 options. They are not meant to be changeable/settable by the users.

 The new sizes are meant to enhance the way WordPress displays images on
 the front-end on larger, high-density devices. They make it possible to
 generate more suitable `srcset` and `sizes` attributes when the users
 upload large images.

 These sizes can still be changed or removed by themes and plugins but that
 is not recommended. The size "names" reflect the image dimensions, so
 changing the sizes would be quite misleading.

 Been wondering if we should make it impossible to change them, only let
 themes and plugins to remove/unset them. Or perhaps we can detect changes
 and output "doing-it-wrong"?
