I would like to remove the operator< and operator > from the float intervals. I
know you use it for sorting, but for that case I would rather have a separate
comparator. The comparator is confusing as it could be interpreted as comparing
left, right, both or just the length.

I think we should assert that the two intervals are already sorted.

This only works if the intervals in both vectors are not self-overlapping. I
think we need to enforce that with an assert. Also, assert that the two are
sorted.

> + static void subtractShapeIntervals(const ShapeIntervals& a, const
ShapeIntervals& b, ShapeIntervals& result)
Assert the expectations of the function (ie. intervals are sorted and not
overlapping)
> Source/WebCore/rendering/shapes/ShapeInterval.h:165
> + if (aValue < bValue) {
I don't like using the operator < here. I think the actual members instead of
the operator "<" would be less confusing. In this case it can be interpreted
two ways: a) aValue.x2 < bValue.x1 or b) aValue.x1 < bValue.x1.
You've used this pattern in multiple place, please update all of them and
remove the operators.
