<Swing Dev> [9] Review request for 8160986 Bad rendering of Swing UI controls with Metal L&F on HiDPI display

[Alexandr Scherbatiy]

Hello,

Could you review the fix:
   bug: https://bugs.openjdk.java.net/browse/JDK-8160986
   webrev: http://cr.openjdk.java.net/~alexsch/8160986/webrev.00

   The proposed fix changes icon shapes drawn by lines to ovals and 
polygons for JRadioButton, JComboBox and JScrollBar components for the 
Metal L&F.

   The screenshots [1] give a hint how UI controls look before and after 
the fix.
