Uh not?
But now you say it, I see that none fontmap is set for the cairo_t at
all - regardless if pango_cairo_show_layout() or
pango_cairo_show_glyph_string() is used. I guess it's pure coincidence
it works with the latter in my code.

In that case yes, I see.

Nothing productive. I only wanted to play with it in order to get used
to pango. In this case I wanted to be be able to call
pango_ft2_font_get_kerning() on a PangoGlyphString.
