<Swing Dev> [9] Review request for 8133919 [macosx] JTable grid lines are incorrectly positioned on HiDPI display

[Sergey Bylokhov]

> Could you review the fix:
>  bug: https://bugs.openjdk.java.net/browse/JDK-8133919
>  webrev: http://cr.openjdk.java.net/~alexsch/8133919/webrev.00
> 
>  Draw lines calls are replaced by SwingUtilities2.drawHLine()/drawVLine in BasicTableUI.
>  The added test is manual because the Robot takes low-resolution screen-shot so necessary artifacts can be hidden.
>  It will  be possible to make the test automated after the fix JDK-8162959 [HiDPI] screenshot artifacts using AWT Robot (see [1])

Probably it Is possible to automate it via drawing to the image in the paint() method?
