Raspberry Pi + JavaFX 3D demo

I think these are the sample apps: http://interactivemesh.org/testspace/j3dmeetsjfx.html

I take that back, the PI HotSpot numbers are generally faster than the RoboVM iOS numbers (but RoboVM is faster than HotSpot when run as an interpreter, obviously). We need to get our benchmark open source (we call it VMBenchmark) so that we can host accurate numbers on the WIKI and everybody can run it on their own systems.

So there are A LOT of opportunities for improvements. The focus so far has been to get something up and running which can actually be used to make apps. I hope I will get the time to optimize things later this year.
