1219 | * calling gtk_window_resize - but that needs to know the size |
1220 | * of the _whole window_, not the drawing area. So what we do |
1221 | * is to set an artificially huge size request on the drawing |
1222 | * area, recompute the resulting size request on the window, |
1223 | * and look at the difference between the two. That gives us |
1224 | * the x and y offsets we need to translate drawing area size |
1225 | * into window size for real, and then we call |
1226 | * gtk_window_resize. |
