--  A Gdk_Window is the physical window that appears on the screen.
--  This is the low-level structure known to the X server or to Win32.
--  All the widgets are internally associated with a specific Gdk_Window,
--  that holds attributes such as the window decoration, whether the window
--  can be interactively resized,...
--
--  On some systems, the graphic server knows how to display non-rectangular
--  windows (this is part of the X extensions).
--
--  If you simply want to create a simply window, you should instead look
--  at the functions provided in Gtk.Window and Gtk.Widget, which are higher
--  level than these. See also the function Gtk.Widget.Get_Window to get the
--  Gdk_Window associated with a widget. Be aware that some of them don't have
--  such windows!
--
--  Scrolling can be implemented in several ways with GtkAda (toplevel
--  scrolling should be done with the Gtk_Scrolled_Window widget, but you
--  might want to handle scrolling yourself). See the function
--  Gdk.Event.Get_Graphics_Expose for more information.
