<AWT Dev> [9] Review request for 8161910: [PIT] regression: HW/LW mixing seems broken on Unity

[Semyon Sadetsky]

Hello,

Please review fix for JDK9:

bug: https://bugs.openjdk.java.net/browse/JDK-8161910

webrev: http://cr.openjdk.java.net/~ssadetsky/8161910/webrev.00/

A regression of the 8036915 in which a new frame dimensioning algo was 
introduced for the Unity WM because the latter differs from other WMs a 
lot.  The algo has a flaw in some scenarios when the extent size event 
is delayed while the initial frame insets were established correctly, 
therefore the frame dimensions do not require any tuning. In this case 
the content window need to be notified right in the extent event handler 
to let the content to receive its new dimensions because subsequent 
XConfigureNotify event may be omitted.
