<AWT Dev> [9] Review Request: 4419271 Provide support for scrolling-mechanisms of non-mouse input-devices

[Sergey Bylokhov]

Hello.

Please review the fix for jdk9.

Support of WM_MOUSEHWHEEL for Swing was added (AWT components were not 
touched), which mostly the code symmetric to the WM_MOUSEWHEEL, except 
that I changed the direction to align it in Swing and OS. It seems that 
this functionality does not work on linux as well, at least I was not 
able to enable it. Will file a separate bug for jdk on linux.
