Arguments: line1-end1 line1-end2 line2-end1 line2-end2 &optional pos-to-return
Returns the point (a position object) at which two line segments
intersect if they do intersect, and nil
otherwise.
The first four arguments are position objects that specify the endpoints of the two line segments.
If pos-to-return
is nil
or unspecified, then a new position
object is created and
returned. Otherwise pos-to-return should be a
position object, which will be modified and returned.
As usual, position objects should contain integers. See make-position.
