Currently the function D3DXQuaternionRotationMatrix evaluates the values 
of the components of the vector from the "trace" whenever this is bigger 
than 0. The literacy discourages this as the error can be very big if 
trace is near 0. From the tests implemented in this patch, it comes out 
that the value with whom trace is compared is 1.0f. Therefore, this 
patch adds tests to verify the cases where trace is between 0.0 and 2.0 
to ensure the expected result.
