 * An AnimBlendTree that calculates its weights using the 1D algorithm from chapter 6 of
 * [Rune Skovbo Johansen's thesis](https://runevision.com/thesis/rune_skovbo_johansen_thesis.pdf).
 *
 * The children sit at points along a single parameter, and the two whose points bracket the
 * current value share the weight between them. This is the tree for one-dimensional blends such
 * as idle, walk and run driven by a speed parameter.
