[cairo] Cut cairo_t out of a cairo_t

[Robert Uhl]

Thanks for your answer!
I did it this way:


cairo_surface_t* surface_full = cairo_get_target(cr_full);

cairo_surface_t* surface_cutout = 
cairo_surface_create_for_rectangle(surface_full, p_border, p_border, 
width_cutout, height_cutout);

cairo_t* cr_cutout = cairo_create(surface_cutout);
cairo_surface_destroy(surface_cutout);

draw(cr_cutout, width_cutout, height_cutout);

cairo_destroy(cr_cutout);
