<dd><p>Develop a panel showing the current aperture and the light curve as judged from that aperture.
Clicking on individual pixels on the aperture will toggle those pixels on or off into the
aperture (which will be updated after closing the plot).
Clicking on the 0th row or column will turn off all pixels in that column or row, respectively.
Will iterate continuously until the figure is closed without updating any pixels.</p>
