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 
- Use Line object isntead of static methods
- Do not rely on Math.sign() as it's not supported on all browsers
- Wrap lines at 80 char width.

f6f42fe09b Improve handling of overlap ambiguity in getIntersection() 
Two passes are needed, first strict, then non-strict, to prevent 'better' next candiates over 'worse' ones.

738cc4c214 Yet another improvement in multiple interseections boolean code. 
This appears to be the one. The only remaining failing cases seem to be linked to getting the same intersection twice now!
