double	osmscout::DistanceToSegment (double px, double py, double p1x, double p1y, double p2x, double p2y, double &r, double &qx, double &qy)
	return the minimum distance from the point p to the line segment [p1,p2] this could be the distance from p to p1 or to p2 if q the orthogonal projection of p on the line supporting the segment is outside [p1,p2] r is the abscissa of q on the line, 0 <= r <= 1 if q is between p1 and p2. More...
