[cp-patches] FYI: JRootPane fixlet

[Roman Kennke]

The JRootPane in Sun's implementation is opaque, so should we do. This
allows for some nice painting optimization (if the root pane isn't
opaque, the painting goes up to the toplevel container, thus jumping out
of Swing and going through the inefficient AWT painting.).

        * javax/swing/JRootPane.java
        (JRootPane): Set opaque property to true.
