We render the source into a cairo_surface_t so that we can render it with cairo directly, rather than having to convert it from a pixbuf every time. We also specify the target window when creating the cairo surface so that rendering can be faster. Using cairo surfaces also allows us to seamlessly support window scales. We also add a GTK_IMAGE_SURFACE source type.
