You cannot access the strided data by both named approach 
(u.s.something) and indexed approach.
The two are completely independent strided formats - one is used for the 
fixed pipeline, and the other is used for the shader pipeline.

I think both of you are wrong, and the correct number is 15 + 
WINED3DDP_MAXTEXCOORD, which is the bigger of the two unioned together.
Only modifying the first 16 will break: normal2, tangent, binormal, 
tessFactor, fog, depth, sample in the fixed pipeline case (true, I don't 
see these being used anywhere right now ...).

Please leave writing of the strided data to the functions designed for 
this purpose.
