1495 * of the _whole window_, not the drawing area. So what we do
1496 * is to set an artificially huge size request on the drawing
1497 * area, recompute the resulting size request on the window,
1498 * and look at the difference between the two. That gives us
1499 * the x and y offsets we need to translate drawing area size
1500 * into window size for real, and then we call
1501 * gtk_window_resize.
1505 * We start by retrieving the current size of the whole window.
1506 * Adding a bit to _that_ will give us a value we can use as a
1507 * bogus size request which guarantees to be bigger than the
1508 * current size of the drawing area.
