[9] Review request for 8151303 [macosx] [hidpi] JButton's low-res. icon is visible when clicking on it

[Alexander Scherbatiy]

Hello,
Could you review the fix:
  bug: https://bugs.openjdk.java.net/browse/JDK-8151303
  webrev: http://cr.openjdk.java.net/~alexsch/8151303/webrev.00

  The AquaUtils does not take into account MultiResolutionImage for 
selected/disabled/lightened images generation.
  The fix also leaves the MultiResolutionCachedImage check because the 
base system icon size can be differ from the requested painted size.

  Thanks,
  Alexandr.
