Revise first line table. Treat the tune title as a paragraph (ragged right). Set the column widths to give a wider and hence larger first line tune graphic. Keep using the cropped first line graphic, and introduce our own gaps between lines to keep the tune separations clear. I did look at using the grpahics borders, but that gives left and right margins too.
