[OpenJDK 2D-Dev] [9] Review Request: 8146042 Offscreen rendering is different from onscreen one

[Semyon Sadetsky]

Hello,

Please review the fix for jdk9.

bug: https://bugs.openjdk.java.net/browse/JDK-8146042
webrev: http://cr.openjdk.java.net/~ssadetsky/8146042/webrev.00/

The root cause is incorrect coordinate rounding in D3D renderer. To fix 
the issue one of fudge factors was adjusted.

Another issue mentioning in the JIRA ticket is taken out as a separate bug.
