Is the following acceptable?

1. Implement IDirectXFileSaveObject::SaveTemplates
2. Create programs/dxfconv as a wine program that uses d3dxof to
convert x files to different encodings (e.g. text -> binary)
3. Write the text encoding for D3DRM_XTEMPLATES in include/rmxftmpl.x
4. Use dxfconv and xxd -i to generate the binary contents of
D3DRM_XTEMPLATES, and add a comment to rmxftmpl.h saying it was
generated from rmxftmpl.x
5. Test to make sure the contents is the same for compatibility.
