Add check of value range in Curve.solveCubic to improve performance

7009fc3ea0 Add check of value range in solveCubic 
Performance of `Curve.solveCubic()` can be improved by first checking if the specified value is within the curve's value range. If it is outside the range, the expensive call to `Numerical.solveCubic()` is not necessary.

c217e963b8 Rough bounds checking for _addBounds() 
Performance of `_addBounds()` can be improved significantly by performing a rough bounds checking first. This is a cheap way to check if the curve can extend the current min or max values at all. Only if the check is passed, further Only if the current bounds can be extended by the curve's bounds, further calculation needs to be done.
Also, if the values of a curve are sorted, the extrema are simply the start and end point.

e564955501 Correclty implement sorting of intercepts 
`Array.sort()` without comparison function does not sort by numeric value, but by unicode characters (103 comes before 93 by this sorting), therefore a simple comparison function is required.

b735a3ec95 Fix getInteriorPoint() 
getInteriorPoint() could return a point outside the path as explained in #1064
This fix excludes curve's start points from intercept detection to prevent double counting, it ensures that all intercepts are collected and the intercepts are sorted by x-value.

9f93f6ee78 Check for prevTime >= tMin and prevTime <= tMax 
Parameter scaling should only be done if the curve was actually split previously. This only happened if prevTime greater tMin and less tMax.
