JFXPanel vs. real world usage

okay, we w#ll do this soon. It's currently inside a bigger project.
Since the performance lag is huge, I am not sure how any application could work ;)

Technical spoken... I have seen the implementation is something like this:

1. creating a standard swing panel
2. call the software rendering process from paintComponent
2.1. basically, inside the rendering the following is done:
	1. capturing the JFX Scene to an IntBuffer. Just this step is very hardware dependent. The capturing from an opengl context is very different for any graphics card.
	2. passing the IntBuffer to java 
	3. draw the IntBuffer to a graphics object

From my perspective this code can be used to get nothing better than 10fps on a current state PC, while
a direct capsulation of the opengl context would be fps unlimited.
