08e78b9a88 feat: adding somme new transformation
* Rotate to rotate the image, !! Some point could be outside of the
  0-4096 range on x and y !!
  you should parameter a center and an angle. All the point will move
  around the center. The angle is un degre.
* Flip vertical: flip all the point verticaly. You should parameter an
  height where all point will flip
* Flip horizontaly. You should parameter an X corrodinate where all
  point will flip around.
