code: public static Point2D_F64 convertNormToPixel(CameraModel param , Point2D_F64 norm , Point2D_F64 pixel ) {
  		return convertNormToPixel(param,norm.x,norm.y,pixel);
  	}
docs: <p>
  Convenient function for converting from normalized image coordinates to the original image pixel coordinate.
  If speed is a concern then {@link PinholeNtoP_F64} should be used instead.
  </p>
  
  NOTE: norm and pixel can be the same instance.
  
  @param param Intrinsic camera parameters
  @param norm Normalized image coordinate.
  @param pixel Optional storage for output.  If null a new instance will be declared.
  @return pixel image coordinate
