Combining JavaFX with native UI and shaders?

[John Hendrikx]

The idea behind JavaFX (and most Java API's) is to provide a platform 
independent API, allowing you to write things once and have it run on 
all supported platforms.  Exposing an API that is only available on one 
platform would go against that idea. You either need to do a lot of 
hacking to reach the underlying metal API's, or use JavaFX only as an 
overlay (having JavaFX run in a transparent child window) while the main 
window is accessed directly (also needs some hacking), or use another 
framework more suited to your purpose (maybe one of the gaming frameworks).
