1028 * calling gtk_window_resize - but that needs to know the size
1029 * of the _whole window_, not the drawing area. So what we do
1030 * is to set an artificially huge size request on the drawing
1031 * area, recompute the resulting size request on the window,
1032 * and look at the difference between the two. That gives us
1033 * the x and y offsets we need to translate drawing area size
1034 * into window size for real, and then we call
1035 * gtk_window_resize.
