Hi, Alexander.
I assume that the code in SG2D.getTransform/setTransform is the same as 
was before the fix of 8000629.
Code in SG2D.getDefaultTransform can be simplified, id do not think that 
GraphicsConfiguration.getDefaultTransform. and 
SG2D.getDeviceConfiguration can return null for NullSurfaceData only.
The test should check that default transform of graphics 
configuration(all screens should be checked) is the same as a transform 
of the Graphics.
The method CGraphicsConfig.getDefaultTransform() can use 
getScaleInstance but it is up to you.
