Feature Request: (Optionally) Scale simulator images to relative physical size

Currently simulator images are displayed so that the device pixels have a 1:1 ratio to (logical) pixels on your computer, which is nice for some things, but also gives a completely incorrect view of the relative scale of devices with different pixel densities.

e.g. The FR745 is 240 x 240 and the Venu (round) is 390 x 390. The Venu appears to be 1.625X as tall/wide as the FR745 in the simulator, although obviously that's not the case in reality. It also makes the text of the Venu look huge.

It would be useful for testing/designing UI elements if the simulator had a "physical scale" mode where device images (and rendered pixels) were scaled according to relative pixel density.

IOW, in "physical scale" mode, I would expect the Venu screen and FR745 screen to be the same size in the simulator (as they are the same physically IIRC), even though the former is 390 x 390 and the latter is 240 x 240. I realize this would lead to aliasing issues, which is why it could be optional.

It would also be nice if this physical scale mode had a way to calibrate the display with a physical watch (e.g. by allowing the dev to resize the image of a watch they own until the monitor image matches the size of the physical device.)

Thanks!
