The generator code is run by the KDED when we don't have a profile for a
If we don't have a config this sets the screen scaling to 2 when it has
an DPI > 1.5*normal DPI. The vertical resolution is also checked that it
matches what you'd find on a high resolution screen to hopefully avoid
issues with bogus EDID.
We may need to tweak this heuristic based on feedback, especially when
want to support fractional scaling.
