For counterclockwise rotation:

                          ┌                              ┐
                          │  cos (theta)  sin (theta)  0 │
[ x' y' 1 ] = [ x y 1 ] * │ -sin (theta)  cos (theta)  0 │
                          │   0            0           1 │
                          └                              ┘
