The distribution was updated to GtkExtra 0.99.14, including a new 3D Plot
widget. The GtkAda.Canvas now provides zooming capabilities. It also draws
curve links with Bezier splines instead of circles. For efficiency, the items
in the canvas are no longer double-buffered. Use Buffered_Items if you want to
keep the old behavior. Button_Press events are now reported when an item is
pressed and the event wasn't used to move the item around. A new function,
named Gtk.Widget.Set_Parent_Window, was added. The documentation was updated.
