    # Typicall text expects a string. But rails views have this interesting
    # concept that they implicitly call `to_s` on all the variables before
    # rendering. So, passing an integer to text fails:
    #
    # pdf.text 10       #=> fails because 10 is not a string
    # pdf.text 10.to_s  #=> works
    #
    # To circumvent this situation, we call to_s on value, and delegate
    # action to actual Prawn::Document.
