    ev-view: Create an EvAnnotationWindow for EvAnnotationMarkups allowing this
    
    Depending on the property can-have-popup of EvAnnotationMarkup,
    EvView will dynamically create an EvAnnotationWindow with some
    default dimension and location, if no EvAnnotationWindow existed
    when creating the EvAnnotationMarkup from the backend.
