+Gtk port to nano-X
+
+STATUS
+
+Once upon a time I got a few apps working, then started merging
+the new features added by Owen (32 bit sizes for windows and buffering).
+Since then I haven't found the time to work on it:-/
+
+
+TODO
+
+Finish internal window manager abstraction or add proper support in nano-X.
+Fix event polling.
+Implement GdkImage, GdkRgb stuff.
+Put generic region code in generic gdk and/or use the region code from nano-X.
+Fix ugly automake stuff for make dist.
+
+TODO in nano-X
+
+We need to be able to clip and change the background of windows at runtime
+for apps to not look so ugly!
+Fonts: wait for better nano-X font implementation.
+Properties on windows.
+
+
+If you want to work on this port or get additional informnation, get in 
+touch with me.
+To get the beast to compile you also need to apply the patch below
+(any auto* wizard here?): the issue of having two gtk libraries in the
+system needs to be addressed too, maybe use libgtk-x11-1.4.so and 
+libgtk-nanox-1.4.so ...
