I did some more experimenting: I replaced the copy_area function with
its contents in the source, which is:

                        gdk_pixbuf_scale(title, display,
                                         i * 8, j * 8,
                                         gdk_pixbuf_get_width(title),
                                         gdk_pixbuf_get_height(title),
                                         i * 8, j * 8, 1, 1,
                                         GDK_INTERP_NEAREST);

Of course, it produced the same garbled output. Then I replaced
GDK_INTERP_NEAREST with the other possible options, namely TILES,
BILINEAR, and HYPER, I got different results. Namely, in everything but
the NEAREST mode, nothing but the top left copy of title appeared. And
in NEAREST mode I got the usual garble.

Help!
