commit f5b5fad66e9c545f332a5f5cf8bd86c7d77caa93

    trace: Add breadcrumb for cairo_image_surface_get_data()
    
    Just emit a marker for when cairo_image_surface_get_data() is called on
    a surface so that we have a breadcrumb for when the pixels are first
    exported. (Though note that pointer may be kept around and used much
    later.)
