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.
