I have added the idea to improve OpenGL backend, which I'm also
willing to mentor. For GTK3 - Caolan is the right guy who knows what
could be improved there performance wise. But OTOH any X11 are
probably pointless as the idea AFAIK is to get rid of those backends
in the long run, so I'm not sure who would even be interested in
mentoring that. :)
