Re: [csswg-drafts] [css-backgrounds] Add a 'hairline' border-width value (#3720)

It seems like at some point these borders might become thinner than the user of this keyword expects.  For example, when printing, or as devices get even-higher-resolution.

Also... with Gecko's border rounding behavior (round down in device pixels, except round values between 0 and 1 device pixels up to 1) you can effectively do this today without facing that problem.  For example, a border with width `0.25px' will be one device pixel, unless there are 8 or more device pixels per CSS pixel.  I think there was some movement of other browsers towards that behavior, but I'm not sure if things have converged.
