Integrating javafx ui into custom (jogl based) OpenGL application

[Philipp Dörfler]

I'd be very interested in integrating pure OpenGL with JavaFX, too.

I imagine that it might be possible to render either the existing OpenGL scene or the JavaFX scene into a framebuffer object with the same resolution and then to share it.
The most important thing is that both share the same OpenGL context, though.

Cheers,
~ Philipp
