Yes, but for effects. SM1-3 version tokens are 0xfffexxyy/0xffffxxyy
for vertex and pixel shaders resp. SM4 version tokens look like
0x000000xy/0x000100xy/0x000200xy for PS/VS/GS. I don't remember what
the version token for d3d9 effects looks like, but this is consistent
with MS's general scheme for D3D/shader file formats.
