[9] Review request for 8069361 SunGraphics2D.getDefaultTransform() does not include scale factor

[Alexander Scherbatiy]

Hello,

Could you review the fix:
  bug: https://bugs.openjdk.java.net/browse/JDK-8069361
  webrev: http://cr.openjdk.java.net/~alexsch/8069361/webrev.00
  SunGraphics2D.getDefaultTransform() now returns transform which 
includes GraphicsConfiguration default transform.

  This can break a compatibility for applications which assumes that 
default Graphics2D transform is always identity
  and restore it as sg2d.setTransform(new AffineTransform()). However, 
this is not now true for HiDPI displays.

Thanks,
Alexandr.
