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 ...
