Hi, Alexander.
A few comments:
- Can you clarify the updated array in BufferedImageGraphicsConfig?
Probably some javadoc will be useful?
The BufferedImageGraphicsConfig caches configs with some types.
Configs with the same type but different scales should be treated as
different configs.
The fix caches configs with scales 1 in the first index of the array
and others in the second.
- It it possible to document the new options somewhere? I recall we
have description of some of related options. Also I suggest to file an
additional issue to make these options crossplatform.
Scaling options scale the size of a window on Windows and Linux but
do not scale it on Mac OS.
If it makes sense I will add the same "sun.java2d.uiScale" option
to these three platforms.
Thanks,
Alexandr.

Hello,
Could you review the fix:
bug: https://bugs.openjdk.java.net/browse/JDK-8073320
webrev: http://cr.openjdk.java.net/~alexsch/8073320/webrev.00
This is an initial part of the HiDPI Graphics support on Windows for
the JEP 263: HiDPI Graphics on Windows and Linux
http://openjdk.java.net/jeps/263
- scale factors are added to surface dates
- window size, events coordinates and font are scaled on native side
- backup buffered image is scaled in SunVolatileImage
- AwtRobot MouseMove() and GetRGBPixels() methods are updated
- GetDpiForMonitor function is used to query the specified monitor
for the horizontal and vertical DPI values.
If it is not available ID2D1Factory::GetDesktopDpi method is used
instead.
- "sun.java2d.uiScale.enabled", "sun.java2d.win.uiScale",
"sun.java2d.win.uiScaleX", and "sun.java2d.win.uiScaleY" options are
added for the testing purposes.
Thanks,
Alexandr.
