      Use shortcuts for Flength · a8465033
      Paul Eggert authored
      When calculating the length of a Lisp object whose type is

      Always set explicit HarfBuzz buffer direction · 066a2b49
      Khaled Hosny authored
      If no direction was given by the caller, I assume the text will be drawn
      left to right, if this is not the case then callers must provide
      sensible direction. Letting HarfBuzz guess the direction is not
      appropriate since shaping and drawing must use the same direction.
      
      Also move hb_buffer_guess_segment_properties() call to the end, so it
      only guessing unset properties, until we completely get rid of it.
