The image loading libraries (tiff, libpng and jpeg) are not really
needed. Perhaps GTK+ refuses to compile without them, but it will
definitely work without them at runtime (being unable to load images of
the corresponding formats of course). Although GTK+ can be configured
to use different back-ends, the only fully working one in Linux is the
X11 based one. So GTK+ also depends on X11 libraries.
