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.

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.

45040abc53 More clean-ups for #773 
- Use local variables instead of array lookups for values used repeatetly, and merge with pre-existing variables.
- Add some more comments and reference to long explaining post in issue.

1231153553 Start cleaning up code from #773

- Do not rely on Math.sign() as it's not supported on all browsers
- Wrap lines at 80 char width.
