    Remove ImpInitOutDevData and ImplDeInitOutDevData in OutputDevice

    All these do is some very, very basic initialization. There is no need
    to lazy load the structure, it should be initialized when OutputDevice
    is created in the constructor and deinitialized in the destructor.

mpOutDevData is never NULL
