Re: include: Add d3dx10.h file (try 3)

I know I told you otherwise earlier, but looking again now: please use
an unsigned literal for DXGI_FORMAT_FROM_FILE too, the definition of
DXGI_FORMAT has a "DXGI_FORMAT_FORCE_UINT" entry so it should use
unsigned values.

While you're at it, you can drop the parentheses from the 3 defines.
