AssetSettingsProvider

AssetSettingsProvider это специализация SettingsProvider класс, преобразующий устаревшие настройки в Unified Settings. К устаревшим относятся любые настройки, которые изменялись через инспектор, например файлы *.asset в папке ProjectSettings. Внутри AssetSettingsProvider создаёт Editor для конкретных Ассетов и создает UI для окна Настройки, обворачивая Editor.OnInspectorGUI функции.

Внутри Unity этот класс используется для оборачивания существующих настроек.
