Thanks for this.

I tried with --compositor=Compositor/als and i'm seeing a very
odd-looking affect where the aircraft appears behind all scenery, even
distant mountains. A sort-of Godzilla affect!

I'm also seeing lots of these diagnostics:

  443.38 /home/jules/flightgear/download_and_compile16c/install/simgear/include/simgear/debug/OsgIoCapture.hxx:37: [WARN]:OSG        Warning: detected OpenGL error 'invalid enumerant' after applying attribute TextureBuffer 0x555557402700

Incidentally http://wiki.flightgear.org/Compositor suggests
'--compositor=Compositor/ALS/als', but this fails and the path isn't in
current fgdata - should it be changed to say
'--compositor=Compositor/als'?

Thanks,

- Jules
