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