ecc1edb6ea Revert d204175d39 
Revert fat-line clipping optimization that checked for straight curves, as unfortunately it wasn't reliable in many edge cases.

Relates to #1263

d204175d39 Improve and optimize fat-line clipping algorithm. 
By checking if subdivided curves are straight and falling back on line-line / line-curve approach if they are.

f16b91e0fe Tests: Implement unit test for #1233 2017-02-21 22:10:08 +01:00

357ff0dd43 Reduce epsilon in fat-line clipping to 1e-12 and adjust unit tests. 
These results make much more sense and the algorithm finds less false positives while still behaving reliably in all edge cases.

340a1e2a5f Rename curve-time in API from 'parameter' to 'time' 
And create separate versions of methods that receive curve-time arguments instead of offsets.

Curve#getNormalAt(time, true) -> #getNormalAtTime(true)
Curve#divide() -> #divideAt(offset) / #divideAtTime(time)
Curve#split() -> #splitAt(offset) / #splitAtTime(time)
Curve#getParameterAt(offset) -> #getTimeAt(offset)
Curve#getParameterOf(point) -> getTimeOf(point)
Curve#getPointAt(time, true) -> #getPointAtTime(time)
Curve#getTangentAt(time, true) -> #getTangenttTime(time)
Curve#getNormalAt(time, true) -> #getNormalAtTime(time)
Curve#getCurvatureAt(time, true) -> #getCurvatureAtTime(time)
CurveLocation#parameter -> #time
Path#split(offset/location) -> #splitAt(offset/location)

Closes #563
