_D_e_s_c_r_i_p_t_i_o_n:

     Converts from character position to x position. (X position is
     measured from the left edge of the run). Character positions are
     computed by dividing up each cluster into equal portions.

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

     pangoGlyphStringIndexToX(object, text, analysis, index, trailing)

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

'object': ['PangoGlyphString']     the glyphs return from 'pangoShape'

  'text': [char]       the text for the run

'analysis': ['PangoAnalysis']   the analysis information return from
          'pangoItemize'

 'index': [integer]     the byte index within 'text'

'trailing': [logical]   whether we should compute the result for the
          beginning ('FALSE') or end ('TRUE') of the character.

_V_a_l_u_e:

     A list containing the following elements: 

 'x.pos': [integer]      location to store result
