You removed it from a d3d8 fixed function FVF-only codepath, and are 
adding it back into a shared codepath.
That function doesn't work properly with vertex declarations, it will 
only work with FVFs, which have different strided layout.
FVFs use fixed semantic index [u.s.position], vdecl asks the shader for 
an index [u.s.input[idx]].

Furthermore, the trace isn't needed for declarations, because they have 
their own (better) traces.
