1406 * that in order to set the size correctly we really need to be
1407 * calling gtk_window_resize - but that needs to know the size
1408 * of the _whole window_, not the drawing area. So what we do
1409 * is to set an artificially huge size request on the drawing
1410 * area, recompute the resulting size request on the window,
1411 * and look at the difference between the two. That gives us
1412 * the x and y offsets we need to translate drawing area size
1413 * into window size for real, and then we call
1414 * gtk_window_resize.

1419 * Adding a bit to _that_ will give us a value we can use as a
