/* Actually double behaves differently depending on DLL version:
* For <= 36, it maps to D3DXPT_FLOAT.
* For 37-40, it maps to zero (D3DXPT_VOID).
* For >= 41, it maps to 39, which is D3D_SVT_DOUBLE (note D3D_SVT_*
* values are mostly compatible with D3DXPT_*).
* However, the latter two cases look like bugs, and a reasonable
* application certainly wouldn't know what to do with them.
* For fx_2_0 it's always D3DXPT_FLOAT regardless of DLL version. */
