Bug: https://bugs.openjdk.java.net/browse/JDK-8147648

Issue: Wrong resolution variant is used as icon in the Unity panel.

Cause: The screen transforms are not applied to find the correct 
resolution variant image in current implementation.

Fix: Applied the screen transforms to graphics object.


 222         int scaleX = (int)tx.getScaleX();
 223         int scaleY = (int)tx.getScaleY();
 224         DataBufferInt buffer = new DataBufferInt(scaleX * width * 
scaleY * height);

  The fix is in the shared code and the scale factor can have floating 
point value on Windows. (for example 1.5).
  It is better to round the final width and height after scaling them.

  Thanks,
  Alexandr.
