Oh, then I seem to miss something. I am not quite up to date with the
actual code, but I consulted the API documentation at cairographics.org.
While I found a way to render _to_ ciro image surfaces, I have found no
way to render a image surface or a RGBA buffer using cairo functionality
I.e. something like
cairo_render_image (cr, img, ctx);
Creating the cairo_image_t (or more generically a device independent
image, aka a RGBA buffer) would be left to other parties.
