    tdf#130768 need to use mnOutOffX/mnOutOffY
    
    in OutputDevice local stuff when want to get
    to pixel coordiantes. These are not often used
    local members of OutputDevice specially used
    in fake-Windows as internal windows offset.
    Thus there is the protected internal replacement
    ImplGetDeviceTransformation() for the usually
    used GetViewTransformation().
    A very problematic thing - we should in principle
    add this to GetViewTransformation() but I am sure
    that this will lead to other problems - argh!
