GtkFB specific widgets.

[Alexander Larsson <alla lysator liu se>]

I'm currently hacking GtkManagedWindow, a widget that derives from
GtkWindow, and adds border rendering and move/resize/close handling.

This is nice to have for programs using GtkFB, but not interesting at all
for X-based programs (except possibly when running without window
manager).

Should i place this widget in the gtk+ cvs tree? If so, should it be built
only when compiling with the linux-fb gdk target?
