1117 * into window size for real, and then we call
1118 * gtk_window_resize.
1122 * We start by retrieving the current size of the whole window.
1123 * Adding a bit to _that_ will give us a value we can use as a
1124 * bogus size request which guarantees to be bigger than the
1125 * current size of the drawing area.
