GtkCellLayout is a particular API that different widgets and objects can
implement. GtkComboBox implements the GtkCellLayout interface for you,
meaning you can call gtk_cell_layout_* functions and pass a GtkComboBox
as the cell_layout argument.

So, for a combo box with a "pixbuf"/"text" row:

lstore = gtk_list_store_new (2, GDK_TYPE_PIXBUF, G_TYPE_STRING);

combo = gtk_combo_box_new_with_model (lstore);

pcell = gtk_cell_renderer_pixbuf_new ();

gtk_cell_layout_pack_start (combo, pcell, FALSE);
gtk_cell_layout_add_attribute (combo, pcell, "pixbuf", 0);

tcell = gtk_cell_renderer_text_new ();

gtk_cell_layout_pack_start (combo, tcell, TRUE);
gtk_cell_layout_add_attribute (combo, tcell, "text", 1);
