submit vertex weights to make World of Warcraft maybe happy (bug 8250)
submit the vertex weights to hw, which will enable broken vertex programs
errorneously using them to work. Note however that this will only work
if glWeight is used, there is no code in mesa at all to deal with weight
vertex array (glWeightPointerARB).
