[MWForum]more "Intersection"

[Wendy Petti]

Following up on Jeff's comparison of Daniel's mathematical code and my
graphical code:  very interesting!  Can anyone explain to me why the output
would be slightly different?  Is this because a line segment of pensize 1,
drawn on a computer screen, is still crude enough to cause a bit of
deviation from a pure mathematical line?

Can we modify Daniel's code to draw the line segments, too, for those of us
who like a visual representation of what we're doing?

Or I suppose we can use mine to draw the line segments while using Daniel's
to output the point of intersection...

(And thanks, Jeff, for the TOWARD utility.)
