Review request for 7122250: [macosx] mouseMoved Events test do not respond in JCK-runtime-7 interactive

[Anthony Petrov]

Hello,

Please review a fix for http://bugs.sun.com/view_bug.do?bug_id=7122250 at:

http://cr.openjdk.java.net/~anthony/x-13-mouseEnterExit-7122250.0/

The root cause of the issue is that AWTView is missing an overridden 
-updateTrackingAreas method that should update the tracking rectangle. 
Adding the override resolves the issue: the mouseEntered/Exited events 
for Window/JWindow instances start to be delivered to Java app.
