/**
 * A control for editing a bezier curve. Ideal for tweaking animation easing values.
 *
 * Integrates the [Cubic Bezier](https://github.com/tweakpane/plugin-essentials#cubic-bezier) control
 * from Tweakpane-creator [Hiroki Kokubun's](https://cocopon.me)  [Essentials
 * plugin](https://github.com/tweakpane/plugin-essentials).
 *
 * _Svelte Tweakpane UI_ extends the original implementation to by supporting tuple values in addition
 * to object values.
 *
 * A utility function `Utils.cubicBezierToEaseFunction()` is also provided to easily convert a cubic
 * bezier value to an easing function compatible with Svelte's built-in
 * [motion](https://svelte.dev/docs/svelte-motion),
 * [transition](https://svelte.dev/docs/svelte-transition), and
 * [animate](https://svelte.dev/docs/svelte-animate) modules.
 *
 * Usage outside of a `<Pane>` component will implicitly wrap the cubic bezier control in `<Pane
 * position="inline">`.
 *
 * Note that _Svelte Tweakpane UI_ embeds a [fork](https://github.com/kitschpatrol/tweakpane-plugin-essentials) of the plugin with build optimizations and [a fix for a performance issue](https://github.com/tweakpane/plugin-essentials/pull/21). The fork also changes the package name from `@tweakpane/plugin-essentials` to `@kitschpatrol/tweakpane-plugin-essentials` for consistency with other plugins.
