<AWT Dev> [9] Review Request: 8154016 [macosx] Some HiDPI code can be removed

[Sergey Bylokhov]

Hello,
Please review the fix for jdk9.

Noop code was removed. It was not removed before, because it was assumed 
that it can be reused for HiDPI support(but it was implemented differently)

Bug: https://bugs.openjdk.java.net/browse/JDK-8154016
Webrev can be found at: http://cr.openjdk.java.net/~serb/8154016/webrev.00
