1584 * people to get around a limitation in gtk. The problem is
1585 * that in order to set the size correctly we really need to be
1586 * calling gtk_window_resize - but that needs to know the size
1587 * of the _whole window_, not the drawing area. So what we do
1588 * is to set an artificially huge size request on the drawing
1589 * area, recompute the resulting size request on the window,
1590 * and look at the difference between the two. That gives us
1591 * the x and y offsets we need to translate drawing area size
1592 * into window size for real, and then we call
1593 * gtk_window_resize.
1597 * We start by retrieving the current size of the whole window.
1598 * Adding a bit to _that_ will give us a value we can use as a
1599 * bogus size request which guarantees to be bigger than the
1600 * current size of the drawing area.
