<Swing Dev> [9] Review request for 8156217 Selected text is shifted on HiDPI display

[Alexandr Scherbatiy]

Hello,

Could you review the fix:
   bug: https://bugs.openjdk.java.net/browse/JDK-8156217
   webrev: http://cr.openjdk.java.net/~alexsch/8156217/webrev.00

   This is the second part of the fix related to the fact that char 
width can be fractional in user space.
http://mail.openjdk.java.net/pipermail/swing-dev/2016-May/005814.html

   The Font.getStringBounds(...) method is used for the fractional 
string width calculation by Swing in user space.

  Thanks,
  Alexandr.
