JavaFX 3D on older GPUs

[Adam Granger]

I just checked Platform.isSupported(ConditionalFeature.SCENE3D), it
returns false. JavaFX + 3D won't work on my linux (ubuntu 12.04) netbook
with an Intel 945GSE GPU chipset either.

Shouldn't javaFX still do software rendering for 3D?.. in the same way
that glxgears still works even if you've not got any drivers installed?
Otherwise it will seriously limit the number of platforms it will work
on...

I'm not after high-end 3D effects, just some basic rotation...
