They are replicated three times, one centered in the screen without viewport, one in the upper left (qurter screen) and

The two viewport scenes get the texture drawn over the center as well, using draw2dimage. This should mark the proper
image position with the top left corner of the texture.
Finally, each scene has a checkbox drawn at the left side, vertically centered. This will show whether GUI elements adhere
