	* gnu/java/awt/peer/gtk/GtkComponentPeer.java
	(handleEvent): Implemented. Handles PaintEvents.
	(paint): Implemented. Use GTK native methods to queue updates
        for this heavyweight peer.
	* gnu/java/awt/peer/gtk/GtkContainerPeer.java
	(handleEvent): Removed.
	* java/awt/Component.java
	(paint): Implemented. Explictly paint the heavyweight peer.
	(update): Clear the background for heavyweight components.
	(paintAll): No need to call peer.paint() anymore.
	(processEvent): Don't process PaintEvents here. It's now done in
	the peer's handleEvent().
	(processPaintEvent): Removed.
	* java/awt/Container.java
	(paint): No need to call super.paint(). Visit heavyweight
	children as well.
	(update): Don't clear the background here.  It's done in
	Component.update().
	(visitChildren): Added check to not recurse into Containers.
	* jni/gtk-peer/gnu_java_awt_peer_gtk_GtkComponentPeer.c
	(filter_expose_event_handler): New method.  Filter unwanted
	expose events while painting heavyweight peers.
	(Java_gnu_java_awt_peer_gtk_GtkComponentPeer_addExposeFilter):
	New method. Connect filter and block pre_event_handler.
	(Java_gnu_java_awt_peer_gtk_GtkComponentPeer_removeExposeFilter):
	New method. Disconnect filter and unblock pre_event_handler.
	(Java_gnu_java_awt_peer_gtk_GtkComponentPeer_gtkWidgetQueueDrawArea):
	New method. Invalidate and update given area.
	* jni/gtk-peer/gnu_java_awt_peer_gtk_GtkEvents.c
	(pre_event_handler): Add checks for unwanted expose events.
