macosx/vout* : in GL mode, create a fullscreen window just like with QT

                instead of switching to OpenGL fullscreen mode (fixes
                unreachable mouse events with DVD menus, fixes the issues
                with people using multiple desktops, etc).
                Fillscreen is temporarily broken, I'll clean this up later.
