add note for reflection under scaling

add images

| Sep 1, 2015 at 7:54 | comment | added | joojaa | You could add some pictures. If you wont I will :P Also might be good to mention order in matrix and row/column orientation is arbitrary. And that rotations in 3d are not comutative. | |
| Sep 1, 2015 at 6:08 | comment | added | ap_ | Great answer. You might want to add that one way to think about affine transforms is that they keep parallel lines parallel. Hence, scaling, rotation, translation, shear and combinations, count as affine. Perspective projection is an example of a non-affine transformation. | |
