1428 * calling gtk_window_resize - but that needs to know the size
1429 * of the _whole window_, not the drawing area. So what we do
1430 * is to set an artificially huge size request on the drawing
1431 * area, recompute the resulting size request on the window,
1432 * and look at the difference between the two. That gives us
1433 * the x and y offsets we need to translate drawing area size
1434 * into window size for real, and then we call
1435 * gtk_window_resize.
1439 * We start by retrieving the current size of the whole window.
1440 * Adding a bit to _that_ will give us a value we can use as a
1441 * bogus size request which guarantees to be bigger than the
1442 * current size of the drawing area.
