JDK-8088262 - [SWT] FXCanvas swallows almost all gesture events
Description
A DESCRIPTION OF THE REQUEST :
On some platforms, especially Mac, SWT is capable of receiving multi-touch gestures from the touchpad. The FXCanvas that embeds JavaFX in an SWT application does receive any of them.

I have implemented the gesture forwarding based on Java 8 in the Github project https://github.com/JanKoehnlein/JavaFX-SWT-Gesture-Bridge
As it uses internal Java APIs I am concerned it won't run on Java 9 anymore, that's why I ported the solution directlyto JavaFX 9. I can provide that as a patch.

JUSTIFICATION :
Multi-touch gestures are a real improvement in the usability of modern UIs.
