title: Android: difference between preRotate and postRotate?
body: <p>What is the difference between preRotate and postRotate? </p>
  
  <p>If I do every translation using postTranslate with preRotate the image, does that mean the image will do all the rotation first before translation. If I wanted to translate an image then rotate the image by its origin of the image. This way will work right...</p>
  
  <p>If I use a postRotate instead of preRotate, I need to move the image back , rotate the postTranslate the image back to the location.</p>
  
  <p>Am my right?  </p>
