/**
 * An AnimBlendTree that calculates its weights using the 2D Cartesian algorithm from chapter 6,
 * section 3 of
 * [Rune Skovbo Johansen's thesis](https://runevision.com/thesis/rune_skovbo_johansen_thesis.pdf).
 *
 * The children sit at points on a plane defined by two parameters, and weights are computed from
 * where the current parameter point lies among them, treating the two axes as independent. Use it
 * when the parameters are unrelated quantities, such as forward speed against turn rate.
