Can't access raw vert data such as tangent.w

See subject line.

Would be nice to have a whole catagory of nodes that specifically give less-messed-with access to the vert data.

Shader forge multiplies the tangent by tangent.w. Which is technically the correct thing to do. But not so much, if I was trying to use the tangent like a 5th UV to pass custom data to the shader because I used up the first 4 UVs :)

And then it gives me the tangent as a float3, when it is in fact a float4. Anywho... raw access would be nice. :)
