1628 * and look at the difference between the two. That gives us
1629 * the x and y offsets we need to translate drawing area size
1630 * into window size for real, and then we call
1631 * gtk_window_resize.
1635 * We start by retrieving the current size of the whole window.
1636 * Adding a bit to _that_ will give us a value we can use as a
1637 * bogus size request which guarantees to be bigger than the
1638 * current size of the drawing area.
