1149 * area, recompute the resulting size request on the window,
1150 * and look at the difference between the two. That gives us
1151 * the x and y offsets we need to translate drawing area size
1152 * into window size for real, and then we call
1153 * gtk_window_resize.
1157 * We start by retrieving the current size of the whole window.
1158 * Adding a bit to _that_ will give us a value we can use as a
