/// <summary>
/// Default state layout for gamepads.
/// </summary>
/// <remarks>
/// Be aware that unlike some other devices such as <see cref="Mouse"/> or <see cref="Touchscreen"/>,
/// gamepad devices tend to have wildly varying state formats, i.e. forms in which they internally
/// store their input data. In practice, even on the same platform gamepads will often store
/// their data in different formats. This means that <see cref="GamepadState"/> will often <em>not</em>
/// be the format in which a particular gamepad (such as <see cref="XInput.XInputController"/>,
/// for example) stores its data.
///
/// If your gamepad data is arriving in a different format, you should extend the "Gamepad" layout and customize its Controls.
///
/// A real-world example of this is the Xbox Controller on macOS, which is supported through HID. Its layout looks like this:
///
/// <example>
/// <code>
/// {
/// "name" : "XboxGamepadOSX",
/// "extend" : "Gamepad",
