	* gnu/java/awt/peer/gtk/GtkWindowPeer.java (setResizable): Use
	"allow_shrink" and "allow_grow" properties.
	* java/awt/Dialog.java: Initialize resizable to true and change
	comments accordingly.  Initialize visible to false in
	constructors.
	* java/awt/Frame.java (dispose): Remove method.
	* java/awt/Window.java (ownedWindows): New field.
	(Window(Window,GraphicsConfiguration)): Add a weak reference to
	owner's ownedWindows vector.
	(finalize): Remove method.
	(hide): Hide owned windows.
	(dispose): Dispose of owned windows.
	(getOwnedWindows): Implement.
	* jni/gtk-peer/gnu_java_awt_peer_gtk_GtkComponentPeer.c: Remove
	unused GtkArg code.
	(set(String,boolean)): Clamp gboolean parameter to g_object_set
	to TRUE or FALSE.
	* jni/gtk-peer/gnu_java_awt_peer_gtk_GtkWindowPeer.c
	(create): Set window's size requisition.
	(connectHooks): Fix indentation.
	(setResizable): Remove function.
	(static setBounds): Likewise.
