- Updates the logic to reflect the Loop-Blinn paper instead of the GPU
gems website.
- Removes the threshold for detecting local cusps. The serpentine
codepath works for these cusps anyway, so what we really want to know
is whether the discriminant is negative.
- Makes sure to not scale the inflection function by 1/0.
- Shifts the inflection function coefficients in d[] so they match the
paper.
- Stores the cubic discriminant in d[0].

- Updates GrPathUtils to computes the KLM functionals directly instead
of deriving them from their explicit values at the control points.
- Updates the utility to return these functionals as a matrix
rather than an array of scalar values.
- Adds a benchmark for chopCubicAtLoopIntersection.
