/* XNA Keys are based on keycodes, rather than scancodes.␊
*␊
* With SDL2 you can actually pick between SDL_Keycode and SDL_Scancode, but␊
* scancodes will not be accurate to XNA4. The benefit is that scancodes will␊
* essentially ignore "foreign" keyboard layouts, making default keyboard␊
* layouts work out of the box everywhere (unless the actual symbol for the keys␊
* matters in your game).␊
*␊
* At the same time, the TextInputEXT extension will still read the actual chars␊
* correctly, so you can (mostly) have your cake and eat it too if you don't␊
* care about your bindings menu not making a lot of sense on foreign layouts.␊
