1124 * and look at the difference between the two. That gives us
1125 * the x and y offsets we need to translate drawing area size
1126 * into window size for real, and then we call
1127 * gtk_window_resize.
1131 * We start by retrieving the current size of the whole window.
1132 * Adding a bit to _that_ will give us a value we can use as a
