[alogo] Bricard exact straight-line mechanism

1) OA = AB = MN = QP
2) AM = PN = ON = MQ = MD = sqrt(2)*(OA)
3) BP = 2(OA)

Use of point X to define conditional intersection-point of two circles (choosing the one which is nearest to X).

All pieces remain fixed in length. The motor drives AM and the mechanism transforms the rotational movement of M, to straight-line movement of the points Q and D. The points of the line DQ describe ellipses (you can see it by attaching pens to them).
