/// <remarks>
/// Animation clips store bindings for material properties by path name, but don't know whether those properties exist on their dependents.
/// Because property names did not change uniformly in the material/shader upgrade process, it is not possible to patch path names indiscriminately.
/// This class provides utilities for discovering how clips are used, so users can make decisions about whether or not to then update them.
/// It has the limitation that it only knows about:
/// - Clips that are directly referenced by an <see cref="Animation"/> component
/// - Clips referenced by an <see cref="AnimatorController"/> used by an <see cref="Animator"/> component
/// - Clips that are sub-assets of a <see cref="PlayableAsset"/> used by a <see cref="PlayableDirector"/> component with a single <see cref="Animator"/> binding
/// It does not know about clips that might be referenced in other ways for run-time reassignment.
/// Recommended usage is to call <see cref="DoUpgradeAllClipsMenuItem"/> from a menu item callback.
/// The utility can also provide faster, more reliable results if it knows what <see cref="MaterialUpgrader"/> was used to upgrade specific materials.
