This could break applications that are requesting this data?

I guess this depends on how we expect the configuration to look. Do we
expect a single DPI/zoom slider? Or one per monitor? Or a global slider
and then per-monitor sliders?

I did a quick test of per-monitor varying DPI:

(NB. the dialog boxes aren't quite the same size, because the height of
the slider is hard set in pixels).

As you can see, in general it looks ok, except that the font hinting
apparently looks naff at 125dpi (I haven't looked at this yet).

In my case, I'd leave both screens at 96dpi, everything is crisp and
readable to me and the DPI difference is not so huge that it's weird.
People with those insanely high resolution displays however may want to
set different DPIs for their monitors so that they can read the text on
their laptop display without squinting.
