That’s not what I meant.

  image-resolution: 1dot;

would mean that each image pixel is one device pixel (“dot”), where a device pixel is the smallest addressable element that can have any of the colors supported by the device.

That’s exactly my point. Whether it makes sense to call the property ‘image-resolution’ then, I’m not sure.
