Hi Laruent,

This sounds promising. I looks forward to taking it for a test drive.

Besides asking other people to help you evaluate it and test it (which 
you just did), the next step would be for you to file a JEP for 
javafx/graphics as you did earlier for client-libs/java2d. It seems like 
something we might consider for JDK 10, once the JDK 10 project is open 
and we start scoping it.
