+-- On mobile the setting is ON or OFF, and ON means one thing: lock the
+-- viewport to the Game Boy's 10:9 at the largest WHOLE multiple this screen
+-- can hold, centred, black around it -- the way an emulator opens a Game Boy
+-- game on a phone.
+--
+-- Three things had to be true and none of them were:
+--
+--   * it had to apply at all.  FaithfulRes.apply returned false on its first
+--     line for mobile, so the OPTIONS row did nothing on Android and iOS.
+--     A phone has no window to resize, so the lock caps the RENDER scale.
+--
+--   * it had to be sized for the device.  The first cut kept the desktop's
+--     absolute 1X-4X ladder, which names a window size you can see on a
+--     desktop and means a different fraction of every phone: 4X was a quarter
+--     of a 1080p display and 5X/6X were not on the list at all.  The scale is
+--     read off the display now, not chosen by the player.
+--
+--   * it had to work in the OVERWORLD.  The world pass deliberately expands
+--     to cover the whole display so letterbox voids become more map.  So the
+--     lock shrank the UI blit while the map kept filling the screen -- and
+--     showed MORE map, since a smaller scale fits more world pixels in.
+--
+-- Pixel perfect throughout: whole multiples only.  The leftover is bars, and
+-- on a 9:20 phone there is a lot of it vertically.  That is what a 10:9
+-- screen looks like on a tall display; stretching to reach the edges would
+-- resample every pixel, which is the one thing this setting exists to refuse.
