   /* TODO(xji): for bidi text "abcDEF" whose display is "abcFEDhij", when click
      right of 'D' and select [D] then move the left selection handle to left
      by one character, it should select [ED], instead it selects [F].
      Reason: click right of 'D' and left of 'h' return the same x-axis position,
      pass this position to FindCursorPosition() returns index of 'h'. which
      means the selection start changed from 3 to 6.
      Need further investigation on whether this is a bug in Pango and how to
      work around it.
