5129fb0050 Do not start with segments with multiple intersections.

7f4d8d54f0 Reduce epsilon in addCurveIntersections() 
1/10 of CURVETIME_EPSILON appears to produce good results. It's probably wise to keep it linked.

1f03b00f99 Remove handling of converged fat-line, as it causes issues. 
Example 23 in #784 was caused by this, and the code's removal has not produced any new issues, while it solved 6 issues in @iconexperience's test suite.

6fb4b7e3c4 Change the way overlaps are detected in lines. 
We don't really care weather they are actually fully collinear, we only really care about the distances from the beginnings- and end-points of one line from the other, since that proximity will affect results elsewhere.
