    Use round caps/joins when generating ink annotation appearances.
    
    This makes ink annotations look less jagged and allows for
    degenerate annotations with a single point to be visible.
    
    Make sure that generated appearance streams for single point
    ink annotation contain a moveto operator and a lineto operator.
    This means that when the path is stroked it will look like a dot.
