That's essentially what PangoGlyphString does.  Combined with the text itself,
ie, PangoGlyphItem, it gives you full information about the clusters.  Check
PangoGlyphItemIter for example, which iterates clusters withing a PangoGlyphItem.

out of the layout and traversing line->runs which is a list of
PangoLayoutRun's.  PangoLayoutRun being a typedef to PangoGlyphItem.
