Sounds reasonable to me, although I wonder if we'll get a bunch of bug
reports complaining their tetris is too big for their screen now. ;)
Alternatively, should we fix display-mm-height to give the correct
value? Presumably it must be possible. I think we manage to display
SVG images at the correct size by calculating the real DPI...
(Except on macOS where the "DPI" is a magic number decided by Apple.)
