* 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.
