Implement the `IFieldEditor` interface to create custom field editors for arbitrary script property types. The interface requires a `Draw` method that renders UI and returns a boolean indicating whether the value changed, plus an out parameter delivering the updated boxed value. Register your editor with `FieldEditorRegistry` to make it discoverable by the script inspector.

Boxing and unboxing patterns are central to `IFieldEditor` implementation. Your `Draw` method receives a boxed object parameter, unboxes it to the target type for editing, and returns the modified value boxed again via the out parameter. This polymorphic approach enables the script inspector to render any type discovered via reflection without compile-time knowledge.

Yes. Create a custom `IFieldEditor` for your struct type—for example, a `ColorFieldEditor` that renders an intuitive color picker. Handle boxing and unboxing of your struct, then register the editor in `FieldEditorRegistry` so `UIPropertyRenderer.DrawPropertyField` uses it for runtime property rendering in the script inspector.

The script inspector uses reflection to discover script properties at runtime, then queries `FieldEditorRegistry` for a matching `IFieldEditor`. The registry returns the appropriate editor, which implements a `Draw` method to render and edit each property polymorphically, handling any type without prior compilation.

You must register custom field editors with `FieldEditorRegistry` for the script inspector to discover them. Registration makes your editor available to `UIPropertyRenderer.DrawPropertyField`, enabling the inspector to render and edit your custom types at runtime.
