39  OnPath = 1 // means that the paths may intersect outside of the real path.
40  // For example two lines in a slight angle might intersect outside of line's Area
41  // When method == Any is selected, the system will return that coordinate, otherwise
42  // the point must be on both
43 
44  // Test = 2 // I am considering to add a 'Test' option, this would allow to set a boolean if
45  // a intersection would have happened. This would potentially speed up line/line intersections
46  // during area selection where usually CAD drawings do contain a lot of lines.
47  // THis would also help during selection of LWPolylines where we can stop testing if
48  // any point would have been found.
