Thanks for these links.
Hmm. Actually these papers tell about general ideas, not such particular
details. After carefully thought for a while, I think the current solution is
quite reasonable now. The question raised when I test on two straight lines,
but linear curves are specially dealt with ON_IntersectLineLine() and other
logic now (overlaps). I've also added some comment to the code to tell about
the possible limitations.
Cheers!
