<AWT Dev> Review Request for 8142861: [TEST_BUG] MultiResolution image: add a manual test for two-display configuration (HiDPI + non-HiDPI)

[Alexander Stepanov]

Hello,

Could you please review the following fix
http://cr.openjdk.java.net/~anazarov/8142861-3/webrev.00/
for
https://bugs.openjdk.java.net/browse/JDK-8142861

Just a single manual test added.
(sorry, I'll remove these unnecessary 'static' modifiers for 
'parentName', 'childName')

Checked on Mac OS X 10.10 (2-display configuration + Quartz) with JDK9 b91

Thanks,
Alexander
