 A window holds a pointer to an `sf::IScreen`. If that pointer is `nullptr`, the above callbacks will be called. If it isn't `nullptr` then the callbacks from the `sf::IScreen` will be called instead.
 You can switch screens via a the `IWindow::SwitchScreen()` function.
 
-To use a screen, you simple derive from `sf::IScreen` and implement the callbacks. `IScreen::OnFocus()` receives the calling `sf::IWindow` as a parameter.
