MacGames 0.1.3

• Age of Empires IV stutters much less. Its x87 math and its software exception handling now run
  together in the Rosetta optimization, where before the exception handling switched the x87 part off.
  Loading a save no longer crashes. Thanks to @DrA1ex
• A HiDPI (Retina) setting on each game's page. It applies to every game in the same Windows
  environment, and Steam or Battle.net restarts to apply it at the next launch. Overwatch keeps it on,
  because its fullscreen canvas needs it
• Age of Wonders 4 is supported, on D3DMetal. MacGames starts the game itself and skips the Paradox
  Launcher, whose window never opens under Wine. The first play installs the game's Windows runtimes,
  and Wine's Retina mode is on for the game alone, so it draws at the display's full size. Thanks to
