<Swing Dev> [9] Review Request: 8029196 Focus border of JButton.buttonType=roundRect is cut off

[Sergey Bylokhov]

Hello.
Please review the fix for jdk 9.
JRS draws all component in specified bounds, but if a component is in 
focus, the frame of focus can exceed the limit of the specified bounds.
The focusable components take this into account in the insets, but we 
cut the focus anyway, because we create the buffer image in bounds size.
In the fix this image was increased by the focus size in each direction.
