Indeed I have, although it was in the 1.2 spec (since that is the
version that mesa 3.2.4 implements, and that is what is in
woody/sarge). The import of it seems to be that you only need define
the clipping planes you want to use, because you will (presumably)
only enable those ones. I think the statements about minimum state
required to implement features that are scattered through the spec are
aimed more at people implementing the spec than people using an
implementation, but I may be very wrong about that.
