<AWT Dev> [8] Review Request: JDK-7002846 Fix for 6989505 may be incomplete

[andrei eremeev]

Hello, AWT Team.

Please review the fix for the issue:
https://bugs.openjdk.java.net/browse/JDK-7002846
The fix is available at:
http://cr.openjdk.java.net/~yan/jdk-7002846/webrev.00/

The problem: WinAPI's function GetPixel returns incorrect value of not 
fully opaque pixel on Intel graphic card.
The idea of the fix is to use getPixels(x, y, 1, 1)[0] which gets pixels 
correctly. But this solution is 2 times slower than we had.
