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

     Computes the extents of a sub-portion of a glyph string. The
     extents are relative to the start of the glyph string range (the
     origin of their coordinate system is at the start of the range,
     not at the start of the entire glyph string).

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

     pangoGlyphStringExtentsRange(object, start, end, font)

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

'object': ['PangoGlyphString']    a 'PangoGlyphString'

 'start': [integer]     start index

   'end': [integer]       end index (the range is the set of bytes with
          indices such that start <= index < end)

  'font': ['PangoFont']      a 'PangoFont'

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

     A list containing the following elements: 

'ink.rect': ['PangoRectangle']  rectangle used to store the extents of
          the glyph string range as drawn or 'NULL' to indicate that
          the result is not needed.

'logical.rect': ['PangoRectangle']  rectangle used to store the logical
          extents of the glyph string range or 'NULL' to indicate that
          the result is not needed.
