vs

The game compiles shaders for vs_5_0/ps_5_0 using d3dcompiler_43 with
D3DCOMPILE_ENABLE_BACKWARDS_COMPATIBILITY flag.

That should trigger semantic remapping:

* vs: output POSITION -> SV_Position
* ps: input POSITION -> SV_Position, output COLORN -> SV_TargetN.

Without compatibility flag semantic names are preserved as is.
