If text is not the empty string (the default), it is
printed on a line of its own to standard output. Otherwise, Line:
is printed. Following this, Point::show() is called on
position and direction.
Point p(1, -2, 3);
Point d(-12.3, 21, 36.002);
Line L0(p, d);
L0.show("L0:");
-| L0:
position: (1, -2, 3)
direction: (-12.3, 21, 36.002)
Line L1 = p.get_line(d);
L1.show("L1:");
-| L1:
position: (1, -2, 3)
direction: (-13.3, 23, 33.002)
Path q = L1.get_path();
q.show("q:");
-| q:
fill_draw_value == 0
(1, -2, 3) -- (-12.3, 21, 36.002);
