I added an option to the configure script to link against gdk instead
of imlib2. Most people already have gdk installed so that way they can
use awesome without installing imlib2, and gdk's pixbuf was explicitly
designed to replace imlib2.
Also, a nice side effect is that GDK works directly with cairo
surfaces, so the process of loading images should be faster, although
since awesome does very little image loading it probably wont have a
noticable impact on performance, but it certainly won't hurt.
