0651eee0c2 No more need for special handling of 'subtract' overlaps. 
This is now taken care of in the code that handles overlaps itself, and the additional code was causing additional issues.

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.

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.
