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

[Alexandr Scherbatiy]

Hello,

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])

Thanks,
Alexandr.
