Thanks Chris.

Is the recommended approached to use cogl directly, cairo or clutter?

FYI, I am using python3 with gtk3 and so far the only code I have been
able to make work with this combination are the clutter examples.

I have some existing opengl. I am looking at either porting it to
cogl/clutter or if there is a way to load it directly with cairo that I
have yet to come across.
