1615 * of the _whole window_, not the drawing area. So what we do
1616 * is to set an artificially huge size request on the drawing
1617 * area, recompute the resulting size request on the window,
1618 * and look at the difference between the two. That gives us
1619 * the x and y offsets we need to translate drawing area size
1620 * into window size for real, and then we call
1621 * gtk_window_resize.
1625 * We start by retrieving the current size of the whole window.
1626 * Adding a bit to _that_ will give us a value we can use as a
1627 * bogus size request which guarantees to be bigger than the
1628 * current size of the drawing area.
