+/**
+ * A class which extends/implements both [WindowInsetsAnimationCompat.Callback] and
+ * [View.OnApplyWindowInsetsListener], which should be set on the root view in your layout.
+ * <p>
+ * This class enables the root view is selectively defer handling any insets which match
+ * [deferredInsetTypes], to enable better looking [WindowInsetsAnimationCompat]s.
+ * <p>
+ * An example is the following: when a [WindowInsetsAnimationCompat] is started, the system will dispatch
+ * a [WindowInsetsCompat] instance which contains the end state of the animation. For the scenario of
+ * the IME being animated in, that means that the insets contains the IME height. If the view's
+ * [View.OnApplyWindowInsetsListener] simply always applied the combination of
+ * [WindowInsetsCompat.Type.ime] and [WindowInsetsCompat.Type.systemBars] using padding, the viewport of any
+ * child views would then be smaller. This results in us animating a smaller (padded-in) view into
+ * a larger viewport. Visually, this results in the views looking clipped.
+ * <p>
+ * This class allows us to implement a different strategy for the above scenario, by selectively
+ * deferring the [WindowInsetsCompat.Type.ime] insets until the [WindowInsetsAnimationCompat] is ended.
+ * For the above example, you would create a [RootViewDeferringInsetsCallback] like so:
+ * <p>
+ * ```
+ * val callback = RootViewDeferringInsetsCallback(
+ * persistentInsetTypes = WindowInsetsCompat.Type.systemBars(),
+ * deferredInsetTypes = WindowInsetsCompat.Type.ime()
+ * )
+ * ```
+ * <p>
+ * This class is not limited to just IME animations, and can work with any [WindowInsetsCompat.Type]s.
