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.
