1204 * area, recompute the resulting size request on the window,
1205 * and look at the difference between the two. That gives us
1206 * the x and y offsets we need to translate drawing area size
1207 * into window size for real, and then we call
1208 * gtk_window_resize.
1212 * We start by retrieving the current size of the whole window.
1213 * Adding a bit to _that_ will give us a value we can use as a
1214 * bogus size request which guarantees to be bigger than the
