Hi All,
Please review the fix for JDK 10.
Bug:
https://bugs.openjdk.java.net/browse/JDK-8159062
Webrev:
http://cr.openjdk.java.net/~psadhukhan/pankaj/JDK-8159062-webrev.00/
Issue:
There are issue with the mouse move events when HIDPI scale is set to
some non-integer value like 1.25, 1.5, 2.5.
Fix:
The issue is due to precision error. In native side in the
awt_Win32GraphicsDevice class, ScaleUp and ScaleDown functions are used
to get scaled value where ceil is used. But in java side, ClipRound is
used which rounds the value instead of ceil. I think we should be doing
round in native side also. This fixes the issue.

Pankaj Bansal
