I am reading the Cairo tutorial, but I want to use Python instead of C. How do I translate this snippet?
cairo_text_extents_t te;
cairo_set_source_rgb (cr, 0.0, 0.0, 0.0);
cairo_select_font_face (cr, "Georgia",
CAIRO_FONT_SLANT_NORMAL, CAIRO_FONT_WEIGHT_BOLD);
cairo_set_font_size (cr, 1.2);
cairo_text_extents (cr, "a", &te);
cairo_move_to (cr, 0.5 - te.width / 2 - te.x_bearing,
0.5 - te.height / 2 - te.y_bearing);
cairo_show_text (cr, "a");
