Method	Description
IsPointInSegmentRange ( Vector2 point, Vector2 start, Vector2 end ) : bool	Check if a point is in the "range" of a segment. This essentially checks if the point is within the segment's bounding box.
IsPointInSegmentRange ( double px, double py, double x1, double y1, double x2, double y2 ) : bool	Check if a point is in the "range" of a segment. This essentially checks if the point is within the segment's bounding box.
LineIntersectionPoint ( Vector2 start1, Vector2 end1, Vector2 start2, Vector2 end2 ) : Vector2?	Calculate the intersection point between two lines (or null if they are parallel).
