Thanks for your hints and explanations.

The reason why I asked was, that I created a GTK3/Cairo application
http://ssalewski.de/PetEd.html.en (which I just try to finish, currently
in Ruby, maybe later ported to Nim) and so I was asked a few times about
cairo drawing performance, and had some discussions about that topic.

For my application performance is good enough, but threading support (or
cairo-gl backed) is generally interesting -- so some more up to date
examples would be great.

I know that there is much better OpenGl support in GTK 3.16 now -- I am
going to test that soon. But Cairo drawing has some benefits too, for
example the various backends, which makes SVG or PDF export easy.
