                * javax/swing/JComponent.java
                (paintChildren): Refactored. The paintChildrenOptimized method
                has been moved back in here. Added locking of the tree and
                only check for completely obscured child components
                when not optimized drawing enabled. Use Graphics.create() to
                protect from irreversible changes.
                (isCompletelyObscured): New helper method.
                (paintComponent): Also use Graphics.create() for Graphics2D,
                to protect from irreverible changes.
                (clipAndTranslateGraphics): Refactored to use more efficient
                iterative (vs recursive) approach.
                * javax/swing/RepaintManager.java
                (getOffscreenBuffer): Create image from root component.
