The Paintable interface from memory the Cairo support was already in
but it changed
some. Its been a few years now since I did the first port :)

It would be nice to tie the GdkWindows to Surfaces/SubSurfaces and move the
DirectFB windows to be a sort of annotation. This would probably open
up implementing
embedding. And make the port more versatile.  The toplevels would then
happen to have a window but it would be nice if its not required.

Next we could take more control over event dispatching and do the hit
detection at the surface level.

One thing is we could use the file descriptor interface and at the fd
to be watched by
the gdk main loop. This would be better I think ?
