matrix_mul, matrix_mul_f - Multiplies two matrices. Allegro game programming library.

       Multiplies two matrices, storing the result in out (this may be a duplicate of one of the input matrices,
       but  it  is faster when the inputs and output are all different). The resulting matrix will have the same
       effect as the combination of m1 and m2, ie. when applied to a point p, (p * out) = ((p * m1) *  m2).  Any
       number  of  transformations  can  be  concatenated  in  this  way. Note that matrix multiplication is not
       commutative, ie. matrix_mul(m1, m2) != matrix_mul(m2, m1).
