Test output from wrl to html frame

Moving your mouse over the objects in the world sends new data to the outFrame.
  The red cone writes one.png into the image in the frame.
  The green sphere writes two.png into the image in the frame.
  The blue cube writes three.png into the image in the frame.
  The purple cylinder writes four.png into the image in the frame.
I use the TouchSensor (though it could be anything that sends an event! to send the isOver FALSE signal when the mouse moves off the objects in order to reload the original image.
