It allows to move most EGL initialization code and EGL surface creation into gles2-renderer, which makes compositor backends less dependent on gles2-renderer. As a side effect weston_output gets a per-renderer state which gles2-renderer uses to store the EGL surface.

I guess we're at a stalemate then.
