I'm not keen to have things show up at different sizes when displayed
on retina vs not on retina. For people (like myself) who have
differently scaled screens, it can result in things magically changing
size, or showing up scaled incorrectly at random. The correct solution
should be to provide hi-res or rescalable icons that are displayed
well at whatever scale the screen has.

Unfortunately that means finding icons that are suitable, and I
suspect for the NS port it may not be super-straightforward to
handle them in the toolbar. I'd have to investigate.

I expect this should be a problem for the PGTK port as well, since it
uses the same scaling method.
