Remove an un-necessary connection to X-Server

[Kalyan]

In GraphicsSurfacePrivate constructor we make a connection to Xserver
        for gaining access to the screens in the display.Immediately(in constructor itself)
        we ask the display from offscreenwindow.
        Removing the former connection as we use the Display returned by offscreenwindow.

Space before Immediately and before the (. Maybe it should be on a new line

Try to make the changelogs easy readable

sorry is m_offScreenWindow initialized here? it is not in the initializer list

m_offScreenWindow is a member variable of GraphicsSurfacePrivate. 
It is created here and increments refcount (static member variable) in its constructor.
It would create a window and open connection to display on calls to 
getXWindow () and display () respectively.
