<Swing Dev> Review Request for 8073454: When de-selecting the "Opaque" checkbox, the pink background is not shown through the togglebuttons that are not selected under the special options "-client -Xmixed -Dswing.defaultlaf=com.sun.java.swing.plaf.windows.WindowsLookAndFeel".

[Semyon Sadetsky]

Hello,

Please review the fix for JDK 9.
The component.isOpaque() is now taken into account in the XP System LAF 
if it is available to do not render component background in case of FALSE.
