the method that takes the CGPoint argument is called from touchesBegan and touchesMoved. the CGPoint method outputs touch coordinates and the touches only register if the touch is within the frame of the image. for factoring purposes i want to be able to call the same method from touchesEnded that will clear the output strings if there is no point, but CGPointZero is a point.
