That is exactly what I wrapped my brain around.
On the VM-Side, Windows and Mac do the sane thing reporting a different scale factor when the majority of window estate is on a new display.
I tried emulating that in the X/Unix implementation.

On the Image side, the scale factor is checked at the same time as the display size, and if it changes, a callback is triggered to update everything interested, such as fonts or morphs.
