I tried to confirm if Pango was being used appropriately by visual
comparison with "cairosimple" [1].

[1]
https://developer.gnome.org/pango/unstable/pango-Cairo-Rendering.html --
look for Example 1.

* I was not able to find a mistake. I don't trust my visual comparison
enough, though.

* Considering that the only difference between cairo-pdf and
cairo-alpha-png is the cairo_*_surface_create() call and that
cairosimple also renders to a PNG file, I considered cairosimple should
failed too, so I compiled and cairosimple. Text rendered correctly.

With this, I'm not sure it's a bug with Cairo.
