In particular,
- We need to link against gdk_pixbuf-2.0 in addition to
gdk_pixbuf_xlib-2.0.
- The header gdk-pixbuf-xlib.h has been moved to the gdk-pixbuf-xlib
directory.
- The function gdk_pixbuf_new_from_file now requires two arguments.
- We need to define GdkColor ourselves since we don't include gdk.h.
