After spending some time with the pango docs, it seems like you might 
want to get each line from the pango layout (with pango_layout_get_line 
maybe), then for each line get all the runs, whose item has an analysis 
which contains a PangoFont.

I'm no pango expert, so there may be an easier way for this.

I'd assume that vim, being a Gtk application, uses pango and therefore 
uses various fonts for displaying the text.
