// The UI-size row of the system option dialog (PORT; 40250 has no counterpart, its UI pixels were screen
// pixels), run by PythonBoot::RunMainScript as module mt_uiscale after mt_framerate. It wraps
// uiSystemOption.OptionDialog's __Load, grows the dialog by one row below the frame-rate row and fills it
// in the same style. The value is app.Get/SetUIHeight (platform/EterBase/UIScaleMode.h): the logical
// height the host lays the UI out at, saved by the host and applied at the next start. The row is only
// added where the setting exists (Android, or MT_UI_HEIGHT on the desktop).
// Strings are UTF-8 here and go through player.AutoHuntLocalize into the locale's code page.
