[ODE] dMarix3

[Jon Watte (ODE)]

dMatrix3 is just a pointer to 12 floats. Those floats are stored in row 
major order, where the fourth colum doesn't matter (i e, you'd typically 
put translation there if it were a 3x4 matrix).

Note that the storage order of, say, OpenGL, is diferent; it also puts 
translation on the right, but stores matrices in column major order.

Cheers,
