1622 * calling gtk_window_resize - but that needs to know the size
1623 * of the _whole window_, not the drawing area. So what we do
1624 * is to set an artificially huge size request on the drawing
1625 * area, recompute the resulting size request on the window,
1626 * and look at the difference between the two. That gives us
1627 * the x and y offsets we need to translate drawing area size
1628 * into window size for real, and then we call
1629 * gtk_window_resize.
1633 * We start by retrieving the current size of the whole window.
1634 * Adding a bit to _that_ will give us a value we can use as a
1635 * bogus size request which guarantees to be bigger than the
1636 * current size of the drawing area.
