Function that evaluates the distance between a point and a segment.

Parameters

fseg	is a pointer to the segment first point
lseg	is a pointer to the segment last point
pt	is a pointer to the considered point
pti	is a pointer to the intersection point

Returns

the distance between the point and the segment
