#   Draws left and right "box" outlines for a string of text
#   in line by line fashion -- useful to create the "body" of
#   a box of text, for example:
#
#       │      Here is some text that          │▒ 
#       │      is created in a box of          │▒ 
#       │      some fixed width, with          │▒ 
#       │      a shadow effect also!           │▒
