You don't seem to be positioning the runs at all.

Guessing at what you want to do, you have two options:

  - Use pango_cairo_layout_path().

  - If you really want to handle each run separately, subclass
PangoRenderer and let pango deal with positioning runs and call back
your method to render each run.
