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.

Closes #795

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.

2167e458ae Since we're using sorting now, we can add all start- / end-point intersections before finding the ones within the curves. 2015-10-03 10:38:45 -05:00

5f706a4a5d Use lower tolerance in bezier clipping code. 
This really should be Numerical.CURVETIME_EPSILON, but I get better results using Numerical.GEOMETRIC_EPSILON. Perhaps Numerical.CURVETIME_EPSILON / 2 is the right value to use though.
