[cp-patches] FYI: Fixed ScrollPaneLayout

[Roman Kennke]

The ScrollPaneLayout implementation has been wrong in several places.
First, the minimum/preferredLayoutSize methods actually modified the
layout, which is not allowed and can have severe performance impact and
malfunction. Second, the layoutContainer method could not properly
determine when the scrollbars should be visible or not. This has lead to
ugly flickers.

        * javax/swing/ScrollPaneLayout.java
        (preferredLayoutSize): Reworked. The old impl used to actually
        modify the layout, which is not allowed.
        (minimumLayoutSize): Reworked. The old impl used to actually
        modify the layout, which is not allowed.
        (layoutContainer): Reworked. The old impl did not properly
determine
        when the scrollbars should be visible and when not.
