Everything is basically in place to resize in such a way, at least
from the main window. However:

- I do not know how may people would think of trying these shortcuts.

- On mobile devices, a convention is a small A and a large A to click
  on, but this would clutter the interface.

- I did not mention it, but tlshell and the gui installer already
  double the font sizes if the pixel dimensions of the screen are
  larger than height 2000 and width 3000 and nothing else is
  configured.  On my macbook, which has a HiDPI screen, I get the
  virtual pixel dimensions, not the much higher actual dimensions,
  and font sizes come out ok without explicit scaling. Apparently
  these are defined in terms of these same virtual pixels.

So I am not sure what would be the best thing to do, if anything.
