I found no documentation for this. Tests show ati inits weight with
(1,0,0,0), but nvidia with (1,0,0,1).
If vertex_blend is not supported nvidia assigns vertex.weight to
vertex.generic1.
Wow depends on weight=(1,0,0,0) or vertex.weight=vertex.generic1 in its
vertex shaders.
I went for atis behavior as it looks more consistent for my novice eye.
