Another request for sf::Window. It should be possible to set the window icon for multiple sizes (16x16, 32x32). I know that both X11 and WinAPI support this, and it really does seem like a useful feature.
Basically, SetIcon() should set different images depending on the given widths/heights, and there should be the ability to unset these various icons. Possibly, a function like sf::Window::UnSetIcon(unsigned int,unsigned int).
