Thank you Quincey for the excellent summary.
NSWindow documentation for the backingScaleFactor indicates "The value of this
property is 2.0 for high-resolution scaled display modes, and 1.0 for all other
cases."
I am just curious, have you actually seen a 3X backing store or is this just a
surmise?
