Please review backport of JDK-8170937 to jdk8u-dev.

Bug: https://bugs.openjdk.java.net/browse/JDK-8170937
Webrev jdk8:  http://cr.openjdk.java.net/~serb/8170937/jdk8/webrev.00/
Webrev jdk12: http://cr.openjdk.java.net/~serb/8170937/webrev.03/

Small difference in jdk12 vs jdk8 exists because of:
  - https://bugs.openjdk.java.net/browse/JDK-8041592
    AWT_Mixing was not ported to jdk8, so no changes in 
  - https://bugs.openjdk.java.net/browse/JDK-8134669
    This fix was not ported to jdk8, so its code was not changed.
  - https://bugs.openjdk.java.net/browse/JDK-8137571
    The fix for HiDPI support was not ported to jdk8, so no code related 
to "scale" was changed/added.

Overall the resulted code in jdk8 is the same as in jdk12, but without 
using of scale factors.

Best regards, Sergey.
