/*!
  paste from the system clipboard using the best-for-us format
  that is present.  try to get the content in the order listed.
  
  \todo currently i have this set so that a ^v or Menu[Edit/Paste] will
  use the CLIPBOARD property and a MiddleMouseClick will use the
  PRIMARY property -- this seems to be the "X11 way" (sigh).
  consider having a preferences switch to allow ^v and Menu[Edit/Paste]
  to use the most recent property... this might be a nice way of
  unifying things -- or it might not -- this is probably an area
  for investigation or some usability testing.
