JDK-8069361 - SunGraphics2D.getDefaultTransform() does not include scale factor
Description
With Apple JDK6 we can call the scale factor like this: toolkit.getDesktopProperty("apple.awt.contentScaleFactor���);

On JDK7 and 8 it's not possible to get the scale factor. Could we please integrate such a possibility?
Comments
This information is now available in JDK 9 for both AWT and JavaFX. The information was made available in the AWT under JDK-8069361 using GraphicsConfiguration.getDefaultTransform() (which was returning IDENTITY in JDK 8, but now returns the scale factors in JDK9). The information was made available in JavaFX using properties on javafx.stage.Window and javafx.stage.Screen under JDK-8091832.
