A DuffPane is now a TibetanPane. A TibetanPane is much more lightweight
but does line breaks correctly. I.e., I refactored DuffPane into two classes. I did this trying to track down a subtle bug in line breaking: 'gye ' breaks after 'gy' sometimes, with the dreng bo on the next line, but only when you resize the window certain ways, and only in Savant (and maybe QD and the translation tool, I don't know) but not in Jskad. I was not successful in finding the bug, but it still exists when I use TibetanPanes instead of DuffPanes in org.thdl.savant.tib.*.
