Hi, Phil, JIm.
New version of the fix:
  - Assumption that we should scale all native surfaces was wrong. In 
case of managed Bufferedimage we shouldn't scale native surface, because 
they are copies 1-1.(CGLSurfaceData.java:60).
  - BufferedContext is not always updates current Paint, because it 
checks transX/transY from sg2d, which is not maintained in the scale mode.
Test: FillTexturePaint.java

Also I found a problem in the sg2d.getTransform(), where invScale does 
not apply to constrainX/Y.
Test: TransformSetGet.java
