bfa0459c52 Go back to using Group for divide() results. 
As they may contain multiple CompoundPaths.

1103c7036f Remove unnecessary isValid() check on segments without intersections. 
It was only causing issues without solving anything.

8c56a1a110 Include _visited checks in isValid() calls. 
This magically reduces the remaining glitches in @iconexperience's test-suite to half.

Relates to #784.

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

3ac3df8d32 Rewrite method for linking and choosing multiple intersections in the same location. 
The special handling of overlaps reduces the amount of remaining glitches substantially.

Relates to #784.

c8132584b9 Pass on original curves to addLocation(), to correctly determine p1 and p2. 
This fixes one glitch in @iconexperience's test suite.

fcdf916863 Some tweaks to debugging code. 
Leave open path artifacts clearly visible for now, so they can be more easily detected.

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

90b4cf7292 No need to check for overlap when determining value for unadjusted 
Since setting only changes behavior if there actually is an overlap.

05bc6afdbb Always give intersection segment priority over current segment if valid. 
Fixes example 22 in #784, doesn't seem to introduce new issues, unlike last time I tried this approach.

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

632eb25f19 Bring back code removed in 11611c8fe2 again. 
But add a _visited check, to get best of both approaches.
