More problems with gdk-pixbuf

[Loban Rahman <loban enigma caltech edu>]

First, thanx James for your previous help. (I must admit that was an
awefully shameful error of mine). ;-)

Now I've got this test code. What it ought to output is a window with
a 4 by 4 grid of the xpm in title_xpm. Instead, the resulting image
is somewhat garbled. If someone could compile it with

gcc `gdk-pixbuf-config --cflags` test.c -o test `gdk-pixbuf-config --libs`

and tell me why the output looks garbled, I'd really appreciate it.
Thanx.
