Fix visual artifacts on Windows when the window is resized

Browse Source 
Now when the user resizes the OS window (a she::Display), it generates
a kDisplayResize she::Event, and this is processed by the UI layer to
redraw the entire ui::Manager.

With this change we remove the obscure "bool" return value in
she::Display::flip() member function.
