     Converts from an index within a 'PangoLayout' to the onscreen
     position corresponding to the grapheme at that index, which is
     represented as rectangle.  Note that 'pos->x' is always the
     leading edge of the grapheme and 'pos->x + pos->width' the
     trailing edge of the grapheme. If the directionality of the
     grapheme is right-to-left, then 'pos->width' will be negative.

_U_s_a_g_e:

     pangoLayoutIndexToPos(object, index, pos)

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

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

 'index': [integer]  byte index within 'layout'

   'pos': ['PangoRectangle']  rectangle in which to store the position
          of the grapheme
