To make the screenshots look good on High DPI displays, we need several images 
(preferably at 100%, 150% and 200% as the most common scales) and use the 
[**`srcset` 
attribute**](https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/img#srcset)
 of the `<img>` element to provide different resolutions.

If you just create a screenshot on (Retina at 200% scale), the screenshots will 
be *too large* and still blurry as browsers will still scale up the screenshots 
to the scale of the display because the [`src` 
attribute](https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/img#src)
 is treated as 100%-scale candidate only.

If we agree to go this way, I can create screenshots on Windows 10 (which still 
uses square window borders) in different resolutions.
