Sets a group of 4 points on a video frame of one camera with the corresponding 4 points on the video frame of another camera. Used when the two cameras are in the 2-Up mode (2-Up mode supported on 3000 only). The point A in the left camera points at the same object as point A in the right camera, and so forth. Users should select 4 points close to the corner of the image for best results. The indexes do not interfere with the [0...4] indexes of the multiple alignment (SetMultipleAlignment_t) command.
