    terminal: Hard wrap text under image printing area
    
    When printing an image over soft-wrapped rows, subsequent widening
    of the window would cause the image's cells to be rewrapped and
    interspersed with the original text, causing the image to be
    overwritten unintuitively.
    
    This is easily fixed by setting the overwritten rows hard wrapped.
