Use correct windowmanager api calling sequence

    For an application which doesn't use qt, but wants to use the windowmanager-service,
    the application needs to call the windowmanager api in the correct sequence.
    Change this sample application to use the correct sequence.

    Rule1:
        Between activeSurface and syncDraw, application should not
        draw anything.
    Rule2:
        An application can change the window size when it received a syncDraw event,
        it does not need to do it in ivi_surface configuration.

    [Patch Sets 2]
    Miss a drawing control flag code, fix it.
