1259 * is to set an artificially huge size request on the drawing
1260 * area, recompute the resulting size request on the window,
1261 * and look at the difference between the two. That gives us
1262 * the x and y offsets we need to translate drawing area size
1263 * into window size for real, and then we call
1264 * gtk_window_resize.
1268 * We start by retrieving the current size of the whole window.
1269 * Adding a bit to _that_ will give us a value we can use as a
