   Note that the correspondences defined here are approximate at best because

   layout, whereas now it refers to a specific physical key on the keyboard,
   regardless of the keyboard layout setting.
   To get comparable behavior to SDL 1.2, code that uses any of the codes below
   in ways like "if (somekey == SDLK_EXCLAIM)" should be changed to the
   equivalent of "if (SDL_GetLayoutKey(somekey) == '!')".
