**Warning**: The returned name is by design not stable across platforms,
e.g. the name for SDL_SCANCODE_LGUI is "Left GUI" under Linux but "Left
Windows" under Microsoft Windows, and some scancodes like
SDL_SCANCODE_NONUSBACKSLASH don't have any name at all. There are even
scancodes that share names, e.g. SDL_SCANCODE_RETURN and
SDL_SCANCODE_RETURN2 (both called "Return"). This function is therefore
unsuitable for creating a stable cross-platform two-way mapping between
strings and scancodes.
Get a human-readable name for a scancode.
