The "standard" for anything today should be the physical display size divided by the pixel count to give the exact resolution for X and Y in DPI. Scaling shoul

The "standard" for anything today should be the physical display size divided by the pixel count to give the exact resolution for X and Y in DPI. Scaling should be relative to that physically correct resolution. We've inherited a lot of baggage and odd conventions, some of which were wrong to begin with. I don't think we should be carrying on with it if we can do better. Having these scaling factors directly correspond to physical reality would be a start.
