     Sets whether to calculate the bidirectional base direction for the
     layout according to the contents of the layout; when this flag is
     on (the default), then paragraphs in 'layout' that begin with
     strong right-to-left characters (Arabic and Hebrew principally),
     will have right-to-left layout, paragraphs with letters from other
     scripts will have left-to-right layout. Paragraphs with only
     neutral characters get their direction from the surrounding
     paragraphs.

     pangoLayoutSetAutoDir(object, auto.dir)

_A_r_g_u_m_e_n_t_s:

'object': ['PangoLayout']  a 'PangoLayout'

'auto.dir': [logical]  if 'TRUE', compute the bidirectional base
          direction from the layout's contents.

_D_e_t_a_i_l_s:

     When 'FALSE', the choice between left-to-right and right-to-left
     layout is done according to the base direction of the layout's
     'PangoContext'. (See 'pangoContextSetBaseDir').

     When the auto-computed direction of a paragraph differs from the
     base direction of the context, the interpretation of
     'PANGO_ALIGN_LEFT' and 'PANGO_ALIGN_RIGHT' are swapped.
