Consider a display system where you have a projected image consisting of two non-overlapping channels. In this case eight corners
in total need to be included in the set of positions to be defined. At the corners where two channels are meeting each other, both
corners may be included in one single position.

Consider a display system where you have a projected image consisting of two overlapping channels. In this case eight corners in
total need to be included in the set of positions to be defined. Also here, the common corners will be included in one single position.
Of course it is possible to include more than two projector corners of the same channel in a single position if they are not too far
away from each other.
