As I said, "at best an approximation", both for the reasons I stated,
and the ones you have also pointed out.
Think of the display wall case; I may want a control panel I use when
I'm close up, though I'm working with many others all over the room for
most applications. So the viewing distance is useful for the default
behavior of applications, but we'll still need to be able to over-ride
