[Pavel Tisnovsky]

Hi,

please review changes made in regression test 
/java/awt/TestArea/UsingWithMouse.java.

Webrev is available at 
http://cr.openjdk.java.net/~ptisnovs/SelectionAutoscrollTest2/

I've added synchronization of scrolling using method 
SunToolkit.realSync(), it seems to works perfectly on RHEL x86_64 + 
Gnome and Fedora 10 i386 + Gnome. Thanks Anthony Petrov for his tip!

This patch can be applied to OpenJDK7 too.

Thanks in advance
