OSGetScreenDpi Method

Returns the dots per inch density of the specified screen. If screen is [/code]-1[/code] (the default value), the current screen will be used.

Note: On macOS, returned value is inaccurate if fractional display scaling mode is used.

Note: On Android devices, the actual screen densities are grouped into six generalized densities:

   ldpi - 120 dpi
   mdpi - 160 dpi
   hdpi - 240 dpi
  xhdpi - 320 dpi
 xxhdpi - 480 dpi
xxxhdpi - 640 dpi

Note: This method is implemented on Android, Linux, macOS and Windows. Returns 72 on unsupported platforms.
