I'm thinking that any NV_vp code might not use vertex.weight, thus explaining
why EXT_vertex_weighting doesn't need to provide the 4 inputs for NVIDIA cards
that would be required for the given ARB_vp samples.

But NVIDIA hardware would probably be no more complicated than detecting
NV_vertex_program, wouldn't it? Does ATI's fglrx driver support
NV_vertex_program? WoW is obviously oblivious to Mesa...

Oh, so Intel would need to implement ARB_vertex_blend for any i965 driver for
the Mac anyway? Nuts.
