Re: d3dx9: Implement D3DXMatrixAffineTransformation2D with tests

[Tony Wasserka]

Hi,
you forgot the WINAPI in front of the function declaration and 
implementation.
Maybe you should add a set_mat(_11, _12, _13, ....) macro to make the 
exp_mat better to read and not that big in size,
However, I think it's better to dynamically calculate the expected 
matrix rather than compare it to hard-coded values (I'm not sure about 
that one though, it's just what _I_ would do). It would at least make 
the whole thing easier be adopted to new tests (of the same function 
with different values).
Best regards,
    Tony
