most important for The GIMP is probably that fact that the object
system has been moved out of GTK+ into GLib/GObject which allows to do
a much cleaner separation between the GIMP core and the user
interface. Of course The GIMP also benefits from all the other
improvements to GLib and GTK+. Here are a few things that come to

 - improved key navigation
 - much better i18n
 - one encoding that rules them all
 - new widgets (stock icons, treeview, textview, ...)

Especially GObject has a whole bunch of nifty features that were not
present in the object system that comes with GTK+-1.2. As an example
I'd suggest you take a look at the newly introduced GimpConfig system
(used to handle user preferences) or check how libgimpmodule allows to
load color selector widgets at runtime.

We could make a lot more use of the new widgets, especially
GtkTreeView, but haven't done yet due to lack of time. The plan is to
reimplement GimpContainerListView using GtkTreeView for GIMP-1.4.

If you ever compiled one of the latest GIMP development releases you
will have noticed that we still make use of deprecated GTK+
widgets. Most certainly even the next stable GIMP release will still
use some deprecated GTK+ functions but it's our long-term goal to get
the GIMP code completely deprecation-free.
