Returns the shortest distance between a given point and this line.

Note: The line is not logically extended to infinity in this function. Only points between the start and end point are considered part of the line.

IntersectionResult Intersection2D	(	const Line &	cOther,

Calculates intersection of 2 lines in 2D. If bSegmentOnly is true it will only.

result the intersection point if it is between the segment endpoints, otherwise the result apply to whole lines.
