compiler.json: resolution vs simulator.json: display.location

It's because of what I call "the button bar" on edge touch devices and other hand held devices.  I first ran into this when the edge 820 was introduced.  The size of the screen is larger than the size of the dc even in a full screen app to leave room for the on screen buttons.

With the 820, here the pink X is using the screen size and the white X, the dc size.

With the 520 (no touch) there is no button bar and the screen and dc are the same.

I know about the virtual button's bar. But a) this warning wasn't there a month ago, b) even looking at the simulator window of montana looks strange now:

it doesn't have the full device's image. I don't remember such a thing. I thing it displayed the bottom part where there are buttons. Same for rino7xx. I remember one of them had in the middle a 4 direction button with arrows up, down, left, right.

There does to be something odd with the Montana in the sim as here's what I see

But the rino looks fine
