On most keyboards, if NumLock is off, pressing "7" on numpad produces "Home", and when NumLock is on, the "7" is produced.
Right now SFML doesn't reflect that, at least on Linux (didn't test on Windows yet). sf::KeyPressed reports "sf::Keyboard::Numpad7" being pressed in both cases. Is this intended behavior?
If not, should we fix it? (I already figured out how to do it).
