[cp-patches] FYI: Some JViewport fixes

[Roman Kennke]

I investigated the JViewport stuff a little more and fixed the following
issues, which should bring JViewport a little closer to the reference
impl's behaviour:

        * javax/swing/JViewport.java
        (ViewListener.componentResized): Only call revalidate instead of
        going through weird reverting code.
        (JViewport): First call updateUI, then set layout.
        (setViewPosition): Don't do anything if there is no real
        change.
        (setView): Don't remove the old component. This is handled by
        addImpl. Call revalidate().
        * javax/swing/ViewportLayout.java
        (layoutContainer): Preferably set view size to it's preferredSize
        instead of its minimumSize.
