map(double)
 Returns a straight line from (x0,y0) to (x1,y1) for t between 1 and 0,
a straight line from (x2,y2) to (x3,y3) for t between tmax1 and tmax
and a coil ( t+pitch*(cos(t*PI)1), height*sin(t*PI) ), first scaled
horizontally and then rotated and translated to run from (x1,y1) to
(x2,y2), for t between 0 and tmax1.
