    // With the default GameControllerInputMapping files, multiple controller inputs may map to the same game input.
    // This is because each controller input maps to a unique standard input, but then multiple standard inputs may map to same game input.
    // To ensure we only show the most "important" controller input for a game input, we define general "display priorities" for each input.
    //
    // For example, MFiGameController.down and MFiGameController.leftThumbstickDown both map to a "down" game input.
    // However, .down has a higher priority than .leftThumbstickDown, so we show .down instead of .leftThumbstickDown.
