Don’t forget to keep the mailing list in CC, like I did here.

From your first message (simplified)

> cairo_surface_t * cairo_surface_main =
> cairo_image_surface_create_for_data(…)
> cairo_t * cairo_image_main = cairo_create (cairo_surface_main);

cairo_set_source_surface(cairo_image_main, cairo_surface_sub, 0 0);

Then probably something like this, to actually paint the source:

cairo_paint(cairo_image_main);
