The mask of a screen might be, but depending on the resolution, the
displayed pixels are not: I can use the VESA mode 1280x1024 (5:4) on
either a 4:3 or 16:9 monitor.

Maybe this is too pedantic and that's the reason why the API only has a
single resolution parameter. I have no experience with, say, printers,
but I thought there you could have 300x600 DPI or such like.

That's a start, thanks,
