title: Android Drawing Path while Zoom and Pinch
body: <p>I'm drawing bitmap and trying to do some drawing over it using Canvas.for drawing i'm adding 
  path whenever user draw something on it surface. I have implemented pinch Zoom and drag features over bitmap but when user Zoom the bitmap and draw something on it then Path doesn't get draw appropriately. I'm using Matrix for pinch zoom and drag features.
  My problem is using the Path with with Matrix. </p>
