Well, I won't be surprised if it actually was pangocairo. Pangocairo
receives an order of magnitude more function calls than libraries higher
in the stack. While Gtk+ may make a call per widget, that will be
broken down into one per line pango calls and one per widget pangocairo
calls that finally loops over individual chars/glyphs, etc, roughly
speaking. Just to give you the idea.
