image of bad text rendering

Setting the antialias font option to CAIRO_ANTIALIAS_BEST makes text rendering
bad, as shown in the following program.

cairo_surface_t *surface = cairo_image_surface_create (CAIRO_FORMAT_ARGB32,
                                                       80, 40);
cairo_t *cr = cairo_create (surface);
cairo_move_to (cr, 5, 30);
cairo_set_font_size (cr, 30);
cairo_font_options_t *font_options = cairo_font_options_create ();
cairo_font_options_set_antialias (font_options, CAIRO_ANTIALIAS_BEST);
cairo_set_font_options (cr, font_options);
cairo_show_text (cr, "hello");
cairo_surface_write_to_png (surface, "out.png");
