1088 * the x and y offsets we need to translate drawing area size
1089 * into window size for real, and then we call
1090 * gtk_window_resize.
1094 * We start by retrieving the current size of the whole window.
1095 * Adding a bit to _that_ will give us a value we can use as a
1096 * bogus size request which guarantees to be bigger than the
1097 * current size of the drawing area.
