8077409: Drawing deviates when validate() is invoked on java.awt.ScrollPane

[mikhail cherkasov]

Hi there,

Could you please  review the fix:
bug: https://bugs.openjdk.java.net/browse/JDK-8077409
webrev: http://cr.openjdk.java.net/~mcherkas/8077409v9/webrev.00/

In ScrollPane, move() is called without considering the quota of
Insets when invoking ScrollPane$PeerFixer.adjustmentValueChanged(). When
validate() is called, drawing deviates to coordinate with Insets
interanlly.

Thanks,
Mikhail.
