Two utility methods would be welcome for VSegment:

  • a method to detect if a point lies on the segment (useful for
    segment selection with the mouse cursor)

  • a method to update a segment's geometry by giving its two
    endpoints (the related constructor already exists, but there is no
    method to do an update of an existing segment using endpoint
    coordinates)

    Done: methods VSegment.intersects() and VSegment.setEndPoints()

    Intersection algorithm supports a tolerance parameter to customize the
    segment's fake thickness w.r.t point containment detection.
