The clip plane number is by intention allways set to 0.
The testcase is just a coocked down version of what is required in principle.
The real application (flightgear) has an unkown number of subtrees where each
of it has 4 clip planes that are different for each subtree. That is just
like the attached example but with 4 planes attache to each ClipNode and with
an unknown number of direct child ClipPlanes just below that topleve Group in
the example.
In theory is must be possible to have a full set of those 6 guaranteed OpenGL
clip planes that are just active for a specific subtree - just like the other
StateAttributes too ?
Greetings
Mathias
