Feature Addition: Apparent Intersection point between two polylines2d

[imrankhan1212]

The current features ezdxf.math.intersection_line_line_2d and ezdxf.math.intersect_polylines_2d
are good but they give intersection points only if the lines or polylines are intersecting each other.

In case, when the lines / polylines are not intersecting or appear to be intersecting, the function does not give you any result. So it is requested to add this feature. I am currently using intersection from "Sympy".

This feature is available in pyautocad and is excellent.

Thanks

If you mean virtual intersections that don't lie on either line, this is supported and is the default for intersection_line_line_2d().

from ezdxf.math import Vec2, intersection_line_line_2d

line0 = Vec2(0, 0), Vec2(1, 0)
line1 = Vec2(2, 1), Vec2(2, 2)

print(intersection_line_line_2d(line0, line1))

prints:

(2.0, 0.0)

Virtual intersections between arbitrary 2D polylines don't seem to be very useful.

intersection between 2 arbitrary polyline2d is actually what I was more interested in.
Anyhow, the library is great. Thanks, and wish you success in future.
