<AWT Dev> [8] Review Request: 7157680 XAWT: Native components should not paint native part on UPDATE event.

[Sergey Bylokhov]

Hello.
Please review the fix for jdk 8.
This fix is for xawt, the same bug was already fixed in lwawt JDK-7125657.
According of 
http://www.oracle.com/technetwork/java/painting-140037.html# update() 
can be used for Incremental painting. And as example this tutorial 
provide this this demo:
http://www.comp.nus.edu.sg/~cs3283/ftp/Java/swingConnect/special_report/painting/UpdateDemo.java
It accidentally work in a xawt, because XCanvasPeer.paintPeer() is noop, 
but if Canvas will be replaced by the Label in the demo, then 
incremental version of the demo does not work.
