da0d01ee09 More work on main boolean code. 
Start addressing self-intersecting paths, and remove resulting open paths for now.

edfabcbbd8 Switch to using 0, 1 instead of tMin, tMax for tangents. 
getTangentAt() can handle that since a while now.

9bd399b5b8 Introduce Curve#isStraight() and use it in splitPath() and divide() to keep the result of splitting straight curves straight. 
Do not use Curve#isLinear(), as that would include curves with collinear handles, and we don't want to set these straight.

718af4527f Boolean: handle linear segments correctly. 
Earlier implementation was unfinished and did not reset some handles to
linear, this caused the winding to be miscalculated.

afc14b9634 Reduce Numerical.TOLERANCE to 1e-6, and use the same value across the boolean code. 
Yields very good results now, across all tests.

cca6606f72 Reduce the amount of path reversing required. 
We don't need paths at clockwise / counter-clockwise orientation. We simply need them oriented the same way, or the opposite way.
